A single piece tag includes a substrate having a first surface and an opposing second surface. A first reactant is applied to the first surface. A first portion of the first reactant is covered by a first release liner. A second reactant is applied to the first release liner which separates the second reactant from the first reactant. A second release liner adjacent the first release liner covers a second portion of the first reactant. The tag is activated by removing the second release liner from the tag to expose the second portion of the adhesive, and the substrate is folded onto itself to contact the second reactant on the first release liner with the first reactant.

An indicator is disclosed that detects the presence of a chemical residue. The indicator includes a substrate having an upper surface and a lower surface and a first portion and a second portion joined at a fold line. The first portion is smaller in area than the second portion. An adhesive coats the upper surface of at least the second portion of the substrate. A first reactant is adhered to the upper surface of the first portion of the substrate. When the second portion is contacted with a surface containing the chemical residue, the residue adheres to the adhesive and when the first portion is subsequently folded along the fold line so that the upper surfaces of the substrate contact each other, a portion of the adhesive on the second portion remains exposed and the first reactant and chemical residue react to provide the color indicia indicating the presence of the chemical residue.

Inspection and testing indicator

A time indicator that provides a color indicia after a predetermined period of time has passed after activation. The time indicator includes a substrate, e.g., a clear or transparent substrate, having an upper surface and a lower surface and a first portion and a second portion joined at a fold line. The first portion is of a smaller area than the second portion. An adhesive coats the upper surface of at least the second portion of the substrate. A first reactant is adhered to the upper surface of the first portion of the substrate and a second reactant is adhered to the upper surface of the second portion of the substrate. When the first portion is folded along the fold line so that the upper surfaces of the substrate contact each other, a portion of the adhesive on the second portion remains exposed. This exposed area may be used to attach the indicator to an article or documents. When so folded the first reactant and second reactant contact each other to activate the indicator and to provide the color indicia after the predetermined period of time after activation passes. In one embodiment, the indicator is used to detect the presence of a chemical residue, e.g., explosive compound residues.

A time indicator assembly including a front part and a back part is disclosed that can easily pass through a printer. The time indicator assembly includes a base substrate forming at least part of the back part having a first surface and a second surface extending between edges. A migrating ink is applied over a portion of the first surface of the base substrate, and a release sheet overlies the migrating ink to prevent migration of the migrating ink toward the front part. In one embodiment, an adhesive is applied over the release sheet and onto the base substrate adjacent at least two of the base substrate edges. The adhesive joins a cover substrate forming at least part of the front part to the base substrate over at least a portion of the release sheet and along the at least two of the base substrate edges. Upon removal of the release sheet, the migrating ink migrates through the adhesive to form an image in the cover substrate. In another embodiment a lift strip is formed in at least one of the front part and back part for easily separating the front part and back part to expose and remove the release sheet.

A long term rapid color changing time indicator includes a front part and a back part. The front part includes a transparent layer, an opaque layer, a colorant layer, and a neutralizing layer. The colorant layer includes a matrix and a colorant having a non-migratory form that does not migrate in the matrix and having a migratory form that migrates in the matrix. The back part has a reactant. When the front part and the back part are placed in contact, the reactant migrates into the neutralizing layer and a portion of the reactant is depleted by a coreactant. The unreacted reactant migrates into the colorant layer and reacts with the non-migratory form of the colorant converting the non-migratory form to the migratory form such that the migratory form of the colorant migrates through the opaque layer to cause a visual color indication in the transparent layer.

A method for continuously producing a plurality of printed and activated time dependent labels. In one embodiment, the method comprises providing a web having a plurality of inked substrates thereon. Each substrate has a migrating ink pattern printed on a surface of the substrate. A transfer printer is provided that has a first ribbon means for applying a timing layer through which the migrating ink bleeds after a predetermined period of time. A second ribbon means is provided for printing variable data. The web of inked substrates is continuously fed through the printer, each inked substrate passing sequentially under the first ribbon means and then the second ribbon means. The first ribbon means is activated to apply the timing layer to a portion of the printed surface of each inked substrate thereunder to produce a coated substrate. The second ribbon means is activated to print the variable data information on each coated substrate thereunder, thus continuously producing a plurality of activated time dependent labels having variable data information printed thereon. In another embodiment for producing a plurality of printed and activated time dependent labels, the web having the plurality of inked substrates thereon is continuously fed through a transfer printer having a single ribbon means. The single ribbon means includes a first ribbon portion for applying a timing layer through which the migrating ink bleeds after a predetermined period of time, and a second ribbon portion for printing variable data. The web is continuously fed through the printer, wherein the first and second ribbon portions pass sequentially over each inked substrate. The first ribbon portion is activated to apply the timing layer to a portion of the printed surface of the inked substrate thereunder, to produce a coated substrate, and then the second ribbon portion is activated to print the coated substrate with the variable data information, thus continuously producing a plurality of activated time dependent labels having variable data information printed thereon.

Time dependent color-changing security indicator

A time indicator rapidly changes color after a specific time interval. The indicator comprises &ldquo;back part&rdquo; that includes a base substrate with a colored dye or colorant deposited on a first surface. A colorant impermeable barrier layer overlays the colorant or colored dye. The indicator further comprises a &ldquo;front part&rdquo; that includes a substrate having an adhesive on a first surface thereof. When the back part and front part are put into adhesive contact with each other, the parts coact with each other to cause the colorant impermeable barrier layer to change to a colorant permeable layer to permit the dye to migrate through the layers to cause a color change visible through the front part.

A security system including a security or identification badge to be worn by a person. The identification badge has a reflective surface that has a predetermined reflective pattern indicating a predetermined identification status of the person wearing the badge. A means is provided for illuminating the reflective surface of the badge with radiation and detecting the reflected radiation from the predetermined reflective pattern. A signal is produced from the detected radiation to indicate the predetermined identification status of the person wearing the badge. Preferably, the badge is illuminated with a visible wavelength of light and the predetermined reflective pattern includes a retroreflective film. Optionally, the reflective surface has a predetermined reflective pattern indicating a predetermined identification status of the person wearing the badge and a means for changing this predetermined reflective pattern to a another predetermined reflective pattern that indicates another predetermined identification status, e.g., an electromagnetic energy source that radiates onto the reflective surface of the badge. Additionally, the a means for illuminating the reflective surface of the badge with radiation can also illuminate the physical characteristic of the person wearing the badge and the means for detecting the reflected radiation can also detect the reflected radiation from the physical characteristic of the person wearing the badge.

A migrating dye indicator that includes a display layer and a base substrate layer. An adhesive layer is on one surface of the display layer for adhesively attaching the display layer to the base layer. The base layer includes a migrating dye capable of migrating through the adhesive layer to the display layer when the adhesive layer is placed in contact therewith. The adhesive layer contains an accelerator for enhancing the migration of the dye through the adhesive layer. The base layer contains a means for absorbing the accelerator into the base layer.

Fixating image in migrating dye indicator

A game card having a hidden game image thereon that is developed over a predetermined period of time. The game card includes a front part and a rear part. The rear part has a migrating ink pattern layer overlaying a rear support member to form a game image. An non-migrating printed pattern layer overlays the rear support member to form a confusion pattern to hide the image. The front part includes a front support layer having an adhesive layer on one side and a front ink display surface on the other side. The adhesive layer is capable of causing the migrating ink pattern to migrate upon contact therewith. Thus when the front part is contacted with the rear part by applying the adhesive layer onto the ink pattern layer, the adhesive layer activates the migration of ink in a selected time interval from the ink pattern layer, through the adhesive layer to the front ink display surface for viewing the game image. Typically, the game image is capable of informing the user whether the game card is a winning card or a losing card.
