Novel polyester compositions useful for image-receiving layers

A composition for an extruded film comprising a blend of a polycarbonate and a polyester copolymer that comprises:

• (a) recurring dibasic acid derived units and polyol derived units, at least 50 mole % of the dibasic acid derived units comprising 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 containing 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 (i) units, if any, derived from a multifunctional polyol having more than two hydroxy groups, based on the total polyol component in the polymer and (ii) units, if any, derived from a polyacid having more than two carboxylic acid groups, including derivatives thereof, based on the total acid derived units.
