Abstract
A dye-donor element for laser-induced thermal dye transfer comprising a support having thereon a dye layer and an infrared-absorbing material which is different from the dye in the dye layer, and wherein the infrared-absorbing material is a Fe(II) complex of the following dye ligand: ##STR1## wherein R represents hydrogen, halogen, cyano, alkoxy, aryloxy, acyloxy, aryloxycarbonyl, alkoxycarbonyl, sulfonyl, carbamoyl, acyl, acylamido, alkylamino, arylamino or a substituted or unsubstituted alkyl, aryl or hetaryl group; PA1 Z represents the atoms necesasry to complete a 5- to 7-membered substituted or unsubstituted nitrogen-containing, heterocyclic, aromatic ring or fused ring system; and PA1 n is 2.
