Abstract

The invention relates to an adhesive composition which is suitable for use on a shaped part of polyester, in particular a polyester film, and comprises a copolyester, optionally in combination with light-sensitive substances, fillers and pigments, whereby the copolyester additionally contains at least one copolymer of vinylidene chloride, preferably in a weight ratio of about 3:1 to 1:1. The adhesive composition can furthermore contain cellulose acyl esters, such as low molecular-weight cellulose acetobutyrate or cellulose propionate. Polybasic oxycarboxylic acids and levelling agents can also be present. The adhesive composition can be employed in mixtures with, for example, light-sensitive lacquer systems.
