Abstract
A dye-donor element comprising a support having thereon a dye layer or an overcoat layer thereon which contains crosslinked elastomeric beads having a Tg of 45.degree. C. or less, the elastomeric beads being made from an acrylic polymer, an acrylic copolymer or a styrenic copolymer, the elastomeric beads having from about 5 to about 40% by weight of a crosslinking agent, the beads having a particle size of from about 0.5 to about 20 .mu.m.

A dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, said dye layer or an overcoat layer thereon containing crosslinked elastomeric beads having a Tg of 45.degree. C. or less, said elastomeric beads being made from an acrylic polymer, an acrylic copolymer or a styrenic copolymer, said elastomeric beads having from about 5 to about 40% by weight of a crosslinking agent, said elastomeric beads having a particle size of from about 0.5 to about 20 .mu.m.
A process of forming a dye transfer image comprising:
- a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and
- b) transferring a dye image to a dye-receiving element comprising a support having thereon a dye image-receiving layer to form said dye transfer image,
- wherein said dye-donor element contains crosslinked elastomeric beads having a Tg of 45.degree. C. or less, said elastomeric beads being made from an acrylic polymer, an acrylic copolymer or a styrenic copolymer, said elastomeric beads having from about 5 to about 40% by weight of a crosslinking agent, said elastomeric beads having a particle size of from about 0.5 to about 20 .mu.m.
A thermal dye transfer assemblage comprising:
- a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and
- b) a dye-receiving element comprising a support having thereon a dye image-receiving layer, said dye-receiving element being in a superposed relationship with said dye-donor element so that said dye layer is in contact with said dye image-receiving layer,
- wherein said dye-donor element contains crosslinked elastomeric beads having a Tg of 45.degree. C. or less, said elastomeric beads being made from an acrylic polymer, an acrylic copolymer or a styrenic copolymer, said elastomeric beads having from about 5 to about 40% by weight of a crosslinking agent, said elastomeric beads having a particle size of from about 0.5 to about 20 .mu.m.
