IMAGE DESTRUCT FEATURE USED WITH IMAGE RECEIVING LAYERS IN SECURE DOCUMENTS

摘要

An image destruct material comprises a release layer positioned between an image receiving layer and a base layer. The adhesion between the release layer and the base layer is greater than adhesion between the release layer and the image receiving layer. The release layer material can be used in secure documents that have an image receiving layer, such as used for dye diffusion, mass transfer, ink jet, and xerographic printing. For example, particular implementations are designed for identification documents with a D2T2 image receiving layer. In these implementations, for example, the release layer is in the form of a patterned coating under the image receiving layer. After information is printed on the image receiving layer, an overlaminate is applied over it. Removal of the overlaminate destroys the printed image on the receiving layer because the relative adhesive properties of the image receiving layer, overlaminate and release layer cause the image to release with the overlaminate at the locations of the coating whereas the remainder of the image remains with the base layer.
