본 발명은 필름과 최종 코팅간의 접착성을 개선하고, 코팅된 필름에 우수한 차단특성을 부여하는 코팅 폴리머 필름용 조성물에 관한 것이다. 코팅 조성물은 아크릴 및/또는 메타크릴 폴리머의 전체 중량 대비 적어도 50 중량%의 겔 함량을 가지고 있는 적어도 하나의 아크릴 및/또는 메타크릴 폴리머, 적어도 하나의 가교제 및 설포닐옥시(Sulphonyloxy) 그룹을 가지는 적어도 하나의 수용성(watersoluble) 또는 수분산성(water-dispersible) 폴리에스테르를 포함한다. 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.
