Patent ID: 8017202

Claim:
A donor element for use in a thermal transfer process comprising a. a support; b. a thermal transfer layer disposed upon the support, wherein the thermal transfer layer is derived from a composition comprising a polycarboxylic acid, a polyhydroxy compound selected from the group consisting of 7,7,11,11-tetrakis[2-(2-hydroxyethoxy)ethoxy]-3,6,9,12,15-pentaoxahepta-decane-1,17-diol and N 1 ,N 1 ,N 7 ,N 7 -tetrakis(2-hydroxyethyl)heptanediamide, and a basic crosslinking agent selected from the group consisting of alkali metal carboxylates, wherein the laser dye is either present in the transfer layer or is present in the heating layer disposed between the support and the thermal transfer layer; and c. a laser dye.
