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 bis(chalcogenopyrylo)polymethine dye. In a preferred embodiment, the bis(chalcogenopyrylo)polymethine dye has the following formula: [Figure] wherein: R1, R2 and R3 each independently 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; or any two of said R1, R2 and R3 groups may be joined together to form a 5- to 7-membered substituted or unsubstituted carboxyclic or heterocyclic ring; or R1 may be joined to Z1 to form a fused 5- or 7-membered substituted or unsubstituted carbocyclic or heterocyclic ring; or R3 may be joined to Z2 to form a fused 5- or 7-membered substituted or unsubstituted carbocyclic or heterocyclic ring; Y1 and Y2 each independently represents sulfur, oxygen, tellurium, or selenium, with the methine chain being joined ortho or para to each of Y1 and Y2; Z1 and Z2 each independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 6 carbon atoms; a substituted or unsubstituted aryl or hetaryl group having from about 5 to about 10 atoms; or the atoms necessary to complete a 5- to 7-membered carbocyclic or heterocyclic ring; each m independently is 1 to 4; n is 1 to 3; and X is a monovalent anion.
