摘要 |
<p>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, characterized in that 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: <CHEM> wherein: each R<1> and R<2> independently represents a substituted or unsubstituted alkyl group having from 1 to 10 carbon atoms or one of R<1> and R<2>, but not both simultaneously, represents a substituted or unsubstituted aryl or hetaryl group having from 5 to 10 atoms; or R<1> and R<2> 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 X<(+)> is a monovalent cation.</p> |
