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.

Actinic radiation curable inks are selectively applied to flexible films which allow the transmission of actinic radiation and then are applied such that the side of the flexible films on which the curable inks are applied contact surfaces of three dimensional substrates. Actinic radiation is applied to the flexible films which cause the ink to cure on the three dimensional substrate. The flexible films are removed leaving the cured ink on the substrates.
