Conformable copolyester film

一种贴体取向的聚合物薄膜，其包括衍生自以下的共聚酯的层：(i)一种或多种二醇；(ii)芳香族二羧酸；和(iii)一种或多种通式为C#-[n]H#-[2n](COOH)#-[2]的脂族二羧酸，其中n是2到8，其中在该共聚酯中芳香族二羧酸存在的量基于该共聚酯中二羧酸组分的总量为60到85摩尔％，其中该共聚酯是无规或者交替共聚酯，和其中在使薄膜经受和维持7％应变进行变形之后，在10分钟的所述变形内，变形后薄膜中的应力降低到低于初始值的60％的剩余值；以及其作为贴体介质用于标志、广告、形象艺术和其他显示应用或者作为用于这类介质的表面层合层的用途。 A conformable oriented polymeric film comprising a layer of copolyester derived from: (i) one or more diol(s); (ii) an aromatic dicarboxylic acid; and (iii) one or more aliphatic dicarboxylic acid(s) of the general formula CnH2n(COOH)2 wherein n is 2 to 8, wherein the aromatic dicarboxylic acid is present in the copolyester in an amount of from 60 to 85 mole % based on the total amount of dicarboxylic acid components in the copolyester, wherein the copolyester is a random or alternating copolyester, and wherein after deformation by subjecting and maintaining the film to 7% strain, the stress within the film immediately after deformation dissipates to a residual value of less than 60% of the original value within 10 minutes of said deformation; and use thereof as a conformable medium for signage, advertising, graphic art and other display applications or as an overlaminate for such media.
