A label sheet including a facestock, and a liner releasably coupled to the facestock. The facestock includes a label and the liner includes a weakened separation line. The weakened separation line at least partially underlies the label. Also, the weakened separation line includes an apex.

Sheet having removable labels

The present invention relates to self-adhesive labels, label sheet assemblies, and related methods. The label sheet assembly includes a release liner assembly having a detachable portion, and a label releasably coupled to the release liner assembly and overlying the detachable portion. Weakened separation lines, a U-shaped cut, and a transverse cut define the detachable portion. The detachable portion is configured to remain coupled to the label as the label is peeled from the release liner assembly in a first direction, and the detachable portion is configured to remain part of the release liner assembly and separate from the label as the label is peeled from the release liner assembly in a second direction.

Labels, label sheet assemblies, and related methods

The present invention is directed to an ink composition resistant to solvent evaporation which may be employed for use in retractable permanent marker pens. Generally, the ink composition of the present invention comprises n-propanol, a pyrrolidone, a tryglyceride, a terpene phenolic resin, and at least one colorant to yield a detectable color when the ink composition is applied to a writable substrate. Additionally, the ink composition may further comprise at least one of polyether modified dimethylpolysiloxane copolymer and silicone glycol surfactant. Optionally, the ink composition may further comprise water.

Ink composition resistant to solvent evaporation

In general, a smear-resistant ink composition according to the present invention comprises: (1) water; (2) at least one glycol selected from the group consisting of diethylene glycol, ethylene glycol, glycerol, and propylene glycol; (3) a pyrrolidone selected from the group consisting of 2-pyrrolidone and 3-pyrrolidone; and (4) at least one colorant that produces a detectable fluorescent color when the ink composition is applied to paper. Preferably, the pyrrolidone is 2-pyrrolidone. In one preferred embodiment, the at least one glycol comprises diethylene glycol and ethylene glycol. In another preferred embodiment, the at least one glycol comprises diethylene glycol, ethylene glycol, and propylene glycol. The composition can comprise other ingredients, such as a basic color stabilizer, a resin, a resin modifier that is a carbonate salt, a biocide, and a nonionic surfactant. The colorants can be formulated to produce a pink, yellow, blue, green, purple, or orange color; other colors are possible.

A versatile method for the manufacturing of image transfer sheets which provide users with cold transferring images without using supplemental heat in the course of image transfer to a wide variety of substrates includes printing an image with water-based ink onto an image transfer sheet that has a coating of water-accepting adhesive. A method of manufacturing image transfer sheets includes first applying a water impermeable layer onto a flexible substrate. A layer of water-activatable adhesive is applied upon the water impermeable layer. The adhesive is then dried in a dryer with dehumidified air. A water permeable detack layer is then applied upon the layer of adhesive. In a particular embodiment, the sheet further includes a water-accepting image holding layer in between the water-accepting adhesive layer and the water impermeable layer. The image holding layer becomes water-resisting when heated to within a range of activation temperatures.

Image transfer sheets and a method of manufacturing the same

A versatile method of cold transferring images without using supplemental heat in the course of image transfer to a wide variety of substrates includes printing an image with water-based ink onto an image transfer sheet that has a coating of water-accepting adhesive. The sheet is then applied to the substrate to transfer only the portions of the adhesive that bear the image onto the substrate, with the remainder of the adhesive remaining attached to the sheet. A method of manufacturing image transfer sheets includes first applying a water impermeable layer onto a flexible substrate. A layer of water-activatable adhesive is applied upon the water impermeable layer. The adhesive is then dried in a dryer with dehumidified air. A water permeable detack layer is then applied upon the layer of adhesive. A sheet for transferring an image that has been printed onto the sheet with a water-based ink has a flexible backing layer and one or more water-accepting layers with water activatable adhesive that are printed with a printing press and/or coated onto the flexible backing layer. A water-impermeable layer is disposed in between the adhesive and the backing layer. A detack layer may be applied onto the layer of adhesive. A water permeable colored, tinted, or reflective water-permeable layer may be between the detack layer and the water-accepting layer, or a colorant may be added to the detack layer. One embodiment includes a water-permeable layer of cross-linker in between the detack layer the water-accepting layer, wherein said water-accepting layer becomes water-resisting when water-based ink flows through said layer of cross-linker and into said water-accepting layer. In another embodiment, the water-accepting layer includes both adhesive and cross-linker, wherein the water-accepting layer is adapted to become water-resisting when the adhesive and the cross-linker react when the water-accepting layer is heated. In another embodiment, the sheet further includes a water-accepting image holding layer in between the water-accepting adhesive layer and the water impermeable layer. The image holding layer becomes water-resisting when heated to within a range of activation temperatures.

An assembly for creating laminated cards for printing by a laser printer has a backing sheet. The backing sheet has a first side with a release coating, and a second side with a printable surface. The assembly also has a card which has been cut from the backing sheet. A lamination sheet adhesively adheres to the first side of the backing sheet and to the cut card. A lamination strip which has been cut from the lamination sheet has a first portion which adheres to and covers one surface of the card. The lamination strip also has an integral second portion which adheres to the backing sheet adjacent to the cut card. The lamination strip maintains the cut card in the same position relative to the backing sheet that the card had prior to being cut. The assembly has a substantially constant thickness and substantially flat upper and lower surfaces so that the assembly can pass through a complex paper path without jamming. A method for creating laminated cards from such an assembly has several steps. A user feeds the assembly into a printer. The printer prints onto the surface of the card. The user removes the card from off the assembly and peels the lamination strip from the assembly. The user then folds the lamination strip to cover the printing surface of the card.

Laminated card assembly

There is provided a label stock laminate which is adapted for passage through office copiers and desk top printers which comprises a laminate of 50 lbs. laminated to a layer of a hot pressure sensitive adhesive resistant to edge ooze, which is in turn laminated to a scored 30 to 35 supercalendared paper release liner, in which the scores require a force normal thereto of between 1 and 3 kilograms to achieve breakage at the score. It is also disclosed a method for manufacture of the improved label stock laminate.

Label stock laminate

A pressure sensitive label assembly includes labels mounted on a backing sheet with the labels having a pressure sensitive adhesive which includes between 45 wt. and 85 wt. % of a copolymer of propylene or ethylene with an aliphatic hydrocarbon having an open chain configuration with between 5 and 7, preferably 6, carbon atoms. The copolymer is preferably amorphous propylene-hexene. The pressure sensitive adhesive also includes liquid and solid tackifiers, and may include U.V. stabilizing and anti-oxidant material.
