Abstract:
1. A dye-donor element for thermal dye transfer comprising a support having on one side a dye layer and on a second side a slipping layer, wherein the slipping layer comprises a first wax comprising a polymer derived from a polyolefin and an ethylenically unsaturated carboxylic acid or ester or anhydride thereof, and at least one other wax and wherein said dye layer comprises at least a magenta dye of the following structure I: wherein X is a NR 3 R 4 group or a hydroxyl group, wherein R 3 and R 4 may be same or different and are independently selected from an alkyl, alkenyl, aryl, aralkyl, or cycloalkyl group; Y 1 and Y 2 each independently are selected from a carbon atom or a nitrogen atom, provided that one of Y 1 and Y 2 is a nitrogen atom; Z is an atomic group necessary to form a 5- or 6-membered nitrogen-containing heterocyclic ring which may be condensed with another ring; and R 1 and R 2 are each independently selected from a hydrogen atom, halogen atom, alkyl, alkenyl, alkoxy, alkylamino, acetamido, sulfonamide, aryl, aralkyl, or cycloalkyl group, wherein said dye donor element has reduced 2× retransfer.
