Polyester compositions useful for image-receiving layers

An extruded film composition comprising a blend of a polycarbonate and a branched polyester copolymer, wherein the branched polyester copolymer comprises recurring dibasic acid derived units and polyol derived units, wherein:

• (a) at least 50 mole % of the dibasic acid derived units comprise dicarboxylic acid derived units each containing an alicyclic ring comprising 4 to 10 ring carbon atoms, which ring is within two carbon atoms of each carboxyl group of the corresponding dicarboxylic acid,
• (b) 25 to 75 mole % of the polyol derived units contain an aromatic ring not immediately adjacent to each hydroxyl group of the corresponding polyol,
• (c) 25 to 75 mole % of the polyol derived units of the polyester are non-aromatic and comprise 2 to 10 carbon atoms, and
• (d) at least 0.1 mole percent, in sum total, of a branching agent comprising (i) units, if any, derived from a multifunctional polyol having more than two hydroxy groups, based on a total polyol component in the copolymer, and (ii) units, if any, derived from a polyacid having more than two carboxylic acid groups, including derivatives thereof, based on a total of acid derived units.
