Tamperproof authority document

摘要

A method for producing an authority document containing a tamperproof right-reading image comprising: a) imagewise-heating a dye-donor element in face-to-face contact with an intermediate dye-receiving element and transferring an image in reverse order to that of an original image, the intermediate dye-receiving element comprising a transparent dye-receiving layer weakly-bonded to a substrate; b) applying heat and/or pressure to laminate a heat-activatable adhesive layer contained on a peelable support to a final receiving element support; c) removing the peelable support to leave the heat-activatable adhesive layer on the final receiving element support; d) placing the intermediate dye-receiving element with the dye-receiving layer containing the image in reverse order, in face-to-face contact with the heat-activatable adhesive layer on the final receiving element support to form an assemblage; e) applying heat and/or pressure to the assemblage sufficient to activate the adhesive; and f) removing the weakly-bonded support of the intermediate dye-receiving element to obtain the authority document having a right-reading image adhesively-bonded to the final receiving element support.
