Conformable copolyester film

Abstract

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.
