COMPOSITION FOR COATING POLYMER FILMS, COATING PROCESS AND COMPOSITE MATERIALS OBTAINED

摘要

The invention relates to a composition intended for coating polymer films, making it possible to improve the adhesion between the film and a final coating, and to confer good barrier properties on the coated film. The coating composition comprises at least one acrylic and/or methacrylic polymer which has a gel content of at least 50% by weight, relative to the total weight of acrylic and/or methacryclic polymer, at least one crosslinking agent and at least one polyester comprising sulphonyloxy groups, which is water-soluble or water-dispersible.
