摘要
There is disclosed donor elements for laser-induced thermal imaging processes containing infrared absorbing croconium dyes of structure (I), wherein R?1, R2, R3, and R4¿ are each independently hydrogen, hydroxyl, halogen, cyano, alkoxy, aryloxy, acyloxy, aryloxycarbonyl, alkoxycarbonyl, sulfonyl, carbamoyl, acyl, acylamido, alkylamino, arylamino, or a substituted or unsubstituted alkyl, aryl, or heteroaryl group; or any of said R?1, R2, R3, and R4¿ are combined with any of R?5, R6, R7, or R8¿ or with each other to form a 5- to 7-membered substituted or unsubstituted carbocyclic or heterocyclic ring; R?5, R6, R7, and R8¿ are each independently hydrogen, a substituted or unsubstituted alkyl or cycloalkyl group having 1 to 6 carbon atoms or a substituted or unsubstituted aryl or heteroaryl group having 5 to 10 atoms; or (R?5 and R6) or (R7 and R8¿) are joined to form a 5- to 7-membered substituted or unsubstituted heterocyclic ring; and n and m are each independently 1 to 4.
