<p>Use of an adhesive dispersion comprising a water-dispersed polymer formed by emulsion copolymerization of a monomer mixture comprising (a) at least one main monomers comprising 1-20C-alkyl(meth) acrylates, vinyl esters, vinyl-aromatic, ethylenically unsaturated nitriles, vinyl halides, vinyl ethers containing alcohols, aliphatic hydrocarbons and/or (meth)acrylamides, (b) at least one 1-20C-hydroxyalkyl(meth) acrylate, (c) at least one ethylenically unsaturated, radically polymerizable monomer, and (d) at least one acid monomer, for laminating high gloss film, is claimed. Use of an adhesive dispersion comprising a water-dispersed polymer formed by emulsion copolymerization of a monomer mixture comprising (a) at least 40 wt.%, preferably 50-98.4 wt.% of at least one main monomers comprising 1-20C-alkyl(meth) acrylates, vinyl esters including containing carboxylic acids having up to 20 carbon atoms, vinyl-aromatics having up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl halides, vinyl ethers containing alcohols having 1-10 carbon atoms, aliphatic hydrocarbons having 2-8 carbon atoms, and/or (meth) acrylamides with one or two double bonds, (b) at least 1 wt.%, preferably 2-20 wt.% of at least one 1-20C-hydroxyalkyl (meth) acrylate, (c) at least 0.6 wt.%, preferably 1-5 wt.% of at least one ethylenically unsaturated, radically polymerizable monomer having at least one glycidyl group, and (d) 0-10 wt.%, preferably 0.1-5 wt.% of at least one acid monomer, for laminating high gloss film, is claimed. Independent claims are included for: (1) a method for laminating a high gloss film, comprising providing a first substrate including polymeric film, preferably transparent polymer film, providing a second substrate including paper, cardboard and paperboard, where the second substrate is printed on the first substrate, applying the adhesive dispersion on at least one surface of the first and/or the second substrates with a subsequent drying step, and laminating the polymer film on the second substrate; (2) high gloss film laminate obtainable by the method; and (3) the adhesive dispersion comprising the water-dispersed polymer formed by emulsion copolymerization of the monomer mixture comprising monomers (a)-(d), where the adhesive dispersion excludes at least one water dispersed polymer P1 formed by emulsion polymerization of a monomer mixture comprising at least 40 wt.% of at least one 4-20C-alkyl (meth)acrylate, which, when its is polymerized as homopolymer, has a glass transition temperature of -30[deg] C or less, at least 0.05 wt.% of at least one (meth) acrylate of formula (I), and at least 0.1 wt.% of at least one acid monomer, the monomer mixture contains at least 0.05 wt.% of glycidyl (meth) acrylate, and the adhesive dispersion further comprises at least one, different from polymer P1, polymer P2 having glycidyl groups.
