ABSTRACT:
The present invention is directed to an image-receiving layer comprising a polyester, or a polyester blend, which exhibits excellent lightfade and high dye transfer efficiency, as well as low materials cost. In particular, the invention relates to an image recording element comprising a support having on one side thereof an image-receiving layer comprising a polyester comprising at least 0.1 mole percent of a multifunctional polyol having more than two hydroxy groups and/or a polyacid having more than two carboxylic acid groups, including derivatives thereof, based on the total acid derived units. The invention is useful, for example, as a dye-receiver element for thermal dye transfer having on one side of the support a dye-image receiving layer. The polyester is especially advantageous for use in dye-receiving layers that are extruded instead of solvent-coated.
