Abstract
A dye-receiving element for thermal dye transfer includes a support having on one side thereof a dye image-receiving layer. Receiving elements of the invention are characterized in that the dye image-receiving layer primarily comprises a crosslinked polymer network formed by the reaction of multifunctional isocyanates with polycarbonate polyols having two terminal hydroxy groups and an average molecular weight of about 1000 to about 10,000.
