Abstract
The present invention relates to 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 the dye layer comprises at least a magenta dye of the Structure I:wherein the dye donor element has reduced 2× retransfer. The present invention also relates to the same slip layer with a dye layer comprising at least a yellow dye of the Structure X:or Structure XI:or Structure XII:or Structure XIII:or wherein the dye layer comprises at least a cyan dye of Structure XX:
