摘要：
A dye-receiving element for thermal dye transfer comprising a support having on one side thereof a dye image-receiving layer, wherein the dye image-receiving layer comprises a crosslinked polymer network formed by the reaction of multifunctional isocyanates with polycarbonate polyols having at least two terminal hydroxy groups and an average molecular weight of about 1000 to about 10,000, and wherein dibutyltin diacetate is used as a catalyst in crosslinking the polymer.
