Abstract
Abstract A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye layer and on the opposite side thereof a slipping layer comprising a lubricating material, and wherein a hydrophilic dye-barrier layer is located between the dye layer and the support, and a subbing layer is located between the dye-barrier layer and the support. The dye-barrier layer prevents wrong-way transfer of dye into the support which provides improved dye transfer densities. The subbing layer improves adhesion between the dye-barrier layer and the support.
