Claims54
A dye-donor element for thermal dye transfer comprising a support having on one side a dye layer and on a second side a slipping layer, wherein the slipping layer comprises a first wax comprising a polymer derived from a polyolefin and an ethylenically unsaturated carboxylic acid or ester or anhydride thereof, and at least one other wax.
A process of forming a dye transfer image comprising:
- (a) imagewise-heating a dye-donor element comprising a support having on one side thereof a dye layer and on a second side a slipping layer comprising a lubricating material, the lubricating material comprising a solid polymer derived from a polyolefin and an ethylenically unsaturated carboxylic acid or ester or anhydride thereof and at least one other wax;
- and
- (b) transferring a dye image to a dye receiving element to form said dye transfer image.
A thermal dye transfer assemblage comprising
- (a) a dye-donor element comprising a support having on one side thereof a dye layer and on the other side a slipping layer comprising lubricating material, wherein the lubricating material comprises a solid polymer derived from a polyolefin and an ethylenically unsaturated carboxylic acid or ester or anhydride thereof and at least one other wax;
- and
- (b) a dye receiving element comprising a support having thereon a dye image-receiving layer,
- wherein the dye-receiving element is in a superposed relationship with the dye-donor element such that the dye layer is in contact with the dye image-receiving layer.
