Abstract:
A process for imparting a dye pattern into a receiving layer comprising the steps of:(a) providing a substrate having a receiving layer thereon and a conductive layer interposed between the substrate and the receiving layer, the conductive layer comprising an optically transparent and electrically conductive material, wherein the receiving layer comprises a light-emitting material;(b) providing a first dye transfer plate having a first dye composition on a first dye transfer surface thereof in the form of a first pattern, wherein the first dye composition contains a first dye;(c) bringing the first dye transfer plate and the substrate together such that the receiving layer and the dye transfer surface arc in contact; and(d) heating the first dye transfer plate and the receiving layer to a first temperature to effect diffusion of the first dye into the receiving layer.
