-0- INFRARED ABSORBING NICKEL-DITHIOLENE DYE COMPLEXES FOR DYE-DONOR ELEMENT USED IN LASER-INDUCED THERMAL DYE TRANSFER Abstract A dye-donor element for laser-induced thermal dye transfer comprising a support having thereon a dye layer comprising a polymeric binder, an image dye and an infrared-absorbing material which is different from the image dye in the dye layer, and wherein the infrared-absorbing material is a nickel-dithiolene dye complex which is located coextensively with the image dye in the dye layer, the dye complex having the following formula: Image or Image wherein: each R1 and R2 independently represents a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms or one of R1 and R2, but not both simultaneously, represents a substituted or unsubstituted aryl or hetaryl group having from about 5 to about 10 atoms; or R1 and R2 may be combined together with the carbon atoms to which they are attached to form a 5- to 7-membered substituted or unsubstituted carbocyclic ring; each Z independently represents the atoms necessary to complete a 6-membered substituted or unsubstituted benzene ring; and ? is a monovalent cation.
