Abstract:
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 first support having thereon a lenticular array on the opposite side thereof;b) imagewise-heating said dye-donor element by means of a laser;c) transferring a dye image to said first support of said lenticular element;d) contacting said dye image with a mordanting element comprising a second support having thereon in order, a release layer and an adhesive layer of an acidic polymer having a Tg less than about 80.degree. C., said adhesive layer of said mordanting element being in contact with the side of said first support which contains said dye image, forming a composite laminate;e) heating said composite laminate to cause said nonionic dye to convert to a cationic dye which is mordanted in said adhesive layer and to cause said adhesive layer to adhere said mordanting element to said lenticular element; andf) removing said second support from said composite laminate, thus forming a diffusion resistant lenticular element.
