Abstract
A dye-donor element for thermal dye transfer comprises a support, a hydrophilic dye barrier/subbing layer comprising a mixture of polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) and a dye layer. The PVA is present in the mixture from about 15 to about 35 weight-percent. The dye-barrier/subbing layer provides improved dye transfer densities.
