-i- INFRARED ABSORBING INDENE-BRIDGED-POLYMETHINE DYES 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 and an infrared-absorbing material which is different from the dye in the dye layer, and wherein the infrared-absorbing material is an indene-bridged-polymethine dye. In a preferred embodiment, the indene-bridged-polymethine dye has the following formula: Image wherein: R represents a substituted or unsubstituted alkyl or cycloalkyl group having from 1 to about 6 carbon atoms or an aryl or hetaryl group having from about 5 to about 10 atoms; R1, R2, R3, R4 and R5 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 R, R1, R2 R3 R4 and R5 groups may be joined together to form a 5- to 7-membered -ii- substituted or unsubstituted carbocyclic or heterocyclic ring, A represents -COR, -CO2R, -CONHR, -CONR2, -SO2R, -SO2NHR, SO2NR2 or -CN; B represents A or hydrogen, -R, -SR, -OR or -NR; or A or B may be joined together to form a 5- to 7-membered substituted or unsubstituted carbocyclic or heterocyclic ring; Y represents a dialkyl-substituted carbon atom, a vinylene group, an oxygen atom, a sulfur atom, a selenium atom, a tellurium atom, NR, or a direct bond to the carbon at the R2 position; Z represents hydrogen or the atoms necessary to complete a 5- to 7-membexed substituted or unsubstituted carbocyclic or heterocyclic ring; and n is 0 to 3.
