Abstract
This invention relates to a dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising an image dye dispersed in a binder, wherein the binder contains hydroxyl groups which have been crosslinked with a titanium alkoxide crosslinking agent and the number of carbon atoms in the alkyl moiety of the alkoxide does not exceed four.
Claims15
A dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising an image dye dispersed in a binder, wherein said binder contains hydroxyl groups which have been crosslinked with a titanium alkoxide crosslinking agent and the number of carbon atoms in the alkyl moiety of the alkoxide does not exceed four.
A process of forming a thermal dye transfer image comprising:
- a) contacting at least one dye-donor element comprising a support having thereon a dye layer comprising an image dye dispersed in a binder with a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer;
- b) imagewise-heating said dye-donor element;
- and
- c) transferring a dye image to said dye-receiving element to form said thermal dye transfer image,
- wherein said binder contains hydroxyl groups which have been crosslinked with a titanium alkoxide crosslinking agent and the number of carbon atoms in the alkyl moiety of the alkoxide does not exceed four.
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 superposed relationship with said dye-donor element so that said dye layer is in contact with said dye image-receiving layer,
- wherein said binder contains hydroxyl groups which have been crosslinked with a titanium alkoxide crosslinking agent and the number of carbon atoms in the alkyl moiety of the alkoxide does not exceed four.
