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 comprises a linear phenoxy resin substantially free of free hydroxyl groups obtained by blocking free hydroxyl groups on a phenoxy resin derived from bisphenol-A and epichlorohydrin with ester, amide, ether, or silyl ether groups.
