Diffusion resistant lenticular element

Abstract

A diffusion resistant lenticular element comprising a support having a lenticular array thereon, the element having thereon an acidic mordanting layer containing a laser-induced, cationic dye image, the mordanting layer being on the side of said support which does not contain said lenticular array. Another embodiment of the invention relates to a process of forming a diffusion resistant lenticular element comprising: a) contacting at least one dye-donor element comprising a support having thereon a dye layer comprising an image dye in a binder having an infrared-absorbing material associated therewith, said image dye comprising a nonionic dye capable of being converted to a cationic dye by means of an acid, with a lenticular element comprising a support having a lenticular array thereon on the opposite side thereof; b) imagewise-heating the dye-donor element by means of a laser; c) transferring a dye image to the support of the lenticular element; d) contacting the dye image with an acidic mordanting layer; and e) heating the element to cause the nonionic dye to convert to a cationic dye which is mordanted in the acidic mordanting layer.
