Abstract: A multilayer composition for packaging comprising a first polymer film, a second film, at least one print layer between the films and a 1 K isocyanate prepolymer adhesive layer between the at least one print layer and one of the films, where the print layer contains a hyperbranched polyester binder containing functional groups selected from the group consisting of —OH, —COOH and —COOR, where R is methyl, ethyl, vinyl, isopropyl, n-propyl, n-butyl, isobutyl, sec-butyl or tert-butyl provides packaging laminates with excellent adhesion. The hyperbranched polyester is for example a polymer of trimethyolpropane and hexahydrophthalic anhydride and optionally a cycloaliphatic diol.
