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.
A process of forming an image-recording element comprising a support having thereon an image-receiving layer, wherein the image-receiving layer 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 within two carbon atoms of each carboxyl group of the corresponding dicarboxylic acid, and at least 25 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 comprise 2 to 10 carbon atoms, and at least 0.1 mole percent, in sum total, of (a) units, if any, derived from a multifunctional polyol having more than two hydroxy groups, based on the total polyol component in the polymer and (b) units, if any, derived from a polyacid having more than two carboxylic acid groups, including derivatives thereof, based on the total acid derived units, wherein the process comprises:
A process of making a dye-receiver element for thermal dye transfer, said dye-receiver element comprising a support having thereon a dye-image receiving layer, wherein the dye-image-receiving layer 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 within two carbon atoms of each carboxyl group of the corresponding dicarboxylic acid, and at least 25 to 75 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 comprise 2 to 10 carbon atoms, and at least 0.1 mole percent, in sum total, of (a) units, if any, derived from a multifunctional polyol having more than two hydroxy groups, based on the total polyol component in the polymer and (b) units, if any, derived from a polyacid having more than two carboxylic acid groups, including derivatives thereof, based on the total acid derived units, wherein the process comprises:
