| 摘要 |
The invention relates to a composition comprising 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, (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 (d) at least 0.1 mole percent, in sum total, of units derived from a multifunctional polyol having more than two hydroxy groups and/or units derived from a polyacid having more than two carboxylic acid groups and derivatives thereof. The invention is also directed to shaped articles, especially extruded films, made from such compositions. Examples of such extruded films are image-receiving layers for use in an image-recording element.
