A heat-transferable security stamp is provided including a carrier sheet, a top coat layer, at least one design layer between the carrier sheet and the top coat layer, a release layer between the carrier sheet and the design layer, and a base coat layer between the release layer and the design layer. The release layer includes a water-borne release component. The base coat layer includes a water-borne base coat component. The design layer includes a water-borne design component. The top coat layer includes a water-borne top coat component. The carrier sheet is resistant to heat above a predetermined heat transfer temperature. The adhesive release component of the release layer is operative to secure the carrier sheet to the base coat layer at temperatures below the heat transfer temperature and to permit release of the carrier sheet from the base coat layer at temperatures above the heat transfer temperature. The base coat component of the base coat layer is operative to function as a barrier between the release layer and the design layer at temperatures above and below the heat transfer temperature. The design component of the design layer is operative to provide an indication of the presence of the security stamp. The top coat component is operative to adhere to a substrate upon contact with the substrate and upon application of heat above the heat transfer temperature. The recited water-borne components may be capable of being borne in water as an aqueous emulsion, an aqueous dispersion, or an aqueous solution.

A security document is provided comprising a finished cellulosic substrate having at least one transparentized portion formed therein. The transparentized portion comprises a transparentizing composition that is applied so as to define an area of increased transparency in the substrate. The area of increased transparency includes at least one thin line and resembles a simulated security thread. The transparentizing composition can be applied to form thin lines in a variety of configurations on one or both sides of the substrate.

Process for the formation of a heat-transferable security stamp entirely free of non-aqueous solvents

Security paper, security documents made from the security paper, and processes for making the security paper, are provided. A filament is bonded and embedded into paper which has previously been manufactured. The filament is bonded to the paper by an adhesive, or by heat and pressure. The filament is embedded into the paper by pressure applied by rolls. The filament may be imprinted with printed matter for visual confirmation of document authenticity. The filament may include any combination of security features, such as reflective filaments, fluorescent filaments, and high tensile strength filaments.

Process for making security paper

The present invention is directed to the deliberate cancellation of MICR-readable documents by applying a penetrating ink through the MICR line of the document wherein the ink contains magnetic particles which disrupt the reading of the MICR line by the MICR reader. The magnetic particles in the ink do not penetrate along with the other ink components, but remain on or near the surface of the document. These extraneous magnetic particles interfere with MICR readers by preventing accurate reading of the encoded MICR characters and cause the MICR reader to reject such a document from normal processing automatically.

Security paper, security documents made from the security paper, and processes for making the security paper, are provided. A groove is formed in paper and a security element is positioned or bonded within the groove. A coating is applied over the security element so that the coating covers at least a portion of the security element and is coplanar with the surface of the paper. The security element may include any combination of security features for verification of document authenticity.
