ABSTRACT:
The invention relates to a process of making an image-recording element comprising a support having thereon an image-receiving layer, wherein the process comprises forming a melt of a polyester material, extruding the melt, and applying the extruded melt to the support for the image-receiving element. The polyester material used for the extruded melt comprises a polyester comprising recurring dibasic acid derived units and polyol derived units, at least 50 mole % of the dibasic acid derived units comprising dicarboxylic acid derived units containing an alicyclic ring, and at least 30 mole % of the polyol derived units containing an aromatic ring not immediately adjacent to each hydroxyl group of the corresponding polyol, 25 to 75 mole % of the polyol derived units of the polyester are non-aromatic, and at least 0.5 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.
