Abstract

Abstract A dye-receiving element for thermal dye transfer comprises a support having thereon a mixture of poly(caprolactone) or a linear aliphatic polyester with one or both of poly(styrene-co-acrylonitile) and a bisphenol A polycarbonate. Dyes which are transferred to this receiving element have improved light stability.
