An anonymous credential system which requires a user who is asserting a credential to have knowledge of the master key of the user who was originally granted that credential. In order for a user to transfer the ability to assert any one of their credentials to another user, they must also transfer their master key to that same user. The master key, however, provides such unlimited rights to its holder that a user is strongly motivated not to share their master key with anyone else. In this manne...

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 lay...

A screen printing process for imprinting an ink design over release coat substrates carried on a web to form heat transferrable labels. The process includes screen printing an ink design image onto the substrate followed by passing the imprinted substrates through a drying section and subsequently transferring the design image to an article. The ink formulation used in the screen printing step is composed of a base ink vehicle containing a polyamide adhesive resin and a film forming component, a...

A photocurable thermally transferable composition containing a multifunctional monomer that is substantially non-liquid at room temperature and a thermoplastic binder is disclosed. The composition is suitable for use in thermal transfer ribbons. After thermal transfer, the compositions are photocured to provide a durable, weatherable image on a graphic article.

To provide a thermally transferable protective sheet which, upon forming a protective layer on a image-receiving member, can provide the protective layer without causing rainbow unevenness.A thermally transferable protective sheet which has a protective layer that comprises a peeling layer and an adhesive layer on at least one portion of one face of a substrate sheet, and is thermally transferable, and the peeling layer and the adhesive layer are respectively constituted by resins that have diff...

A process and composition are provided that provide for thermal transfer of ink compositions and eliminate the need to prepare articles such as sign faces, particularly flexible sign faces, by painting with ink compositions that contain solvents. The present process and composition permit thermal transfer from a carrier to a receptor at low temperatures with the use of vacuum pressure. The transferred ink adheres tenaciously to the receptor and is flexible.

A computer printer compatible index tabs assembly that includes a carrier sheet recognizable by any of a wide variety of computer compatible printing devices. The carrier sheet includes a plurality of self-adhesively secured tabs each formed from a resilient, durable thin film. The self-adhesive is formulated to either permanently or releasably adhere to a peripheral edge of a sheet of material which is to be tagged, labeled or indexed. After printing, the index tab is transferred from the carri...

A process for transferring a holographic image from a conventional polymeric support to a foil support is described in this invention. A host of images may be envisioned and since this image, on a foil support, may then be wound up in a roll, it can be used as a wrapping element for a host of applications such as in the candy and gum industry; wrapping foils; etc. This element and process permits the wide spread use of such holographic images, such use not being available until now.

This invention relates to holographic images formed by a unique process for various security and decorative purposes. Also, this invention relates to aluminized roll-stock holographic images formed on a plastic layer. Further, this invention relates to elements and process for transferring holographic images to yet another substrate. The invention relates to a unique process for transferring holographic images to a relatively inexpensive substrate which permits a wide-spread use of the holograph...

To provide a transferable cover-up article which insures correct adhesion of the cover-up substrate to an adherend, has sufficient masking property and also enables removal of the cover-up substrate. The transferable cover-up article 10 of the present invention comprises a light-transmitting backing 11 and a cover-up substrate 12 laminated on the backing 11 through a removable adhesive 13, the substrate 12 is smaller than the backing 11 and a removable adhesive 13 is laminated on the surface of ...
