Abstract
Abstract A dye-donor element for laser-induced thermal dye transfer comprising a support having thereon a dye layer which also contains an infrared-absorbing material which is different from the dye, and wherein the infrared-absorbing material is a quinoid dye derived from an anthraquinone or naphthoquinone having the following formula: ##STR1## wherein: Z represents the atoms necessary to complete a 5- to 7-membered substituted or unsubstituted carbocyclic or heterocyclic ring; each R independently represents hydrogen, a substituted or unsubstituted alkyl or alkoxy group having from 1 to about 6 carbon atoms or an aryl or hetaryl group having from about 5 to about 10 atoms; m is 4; and n is 2.
