ABSTRACT:
A dye-donor element for thermal dye transfer comprises a support, a hydrophilic dye-barrier/subbing layer comprising poly(butyl acrylate-co-2-aminoethyl methacrylate-co-2-hydroxyethyl methacrylate), poly(N-isopropylacrylamide-co-2-aminoethyl)-methacrylate-co-(2-hydroxyethy l methacrylate), poly[(2-chloroethyl)acrylamide-co-ethacrylic acid],or gelatin nitrate and a dye layer. The dye-barrier/subbing layer provides improved dye transfer densities.
