Patent ID: 8084136

Claim:
A heat-sealable coating system, comprising: a film-forming dispersion, comprising a polymer A which is a polyester or a polyester mixture, a polymer B which is a (meth)acrylate homo- and/or copolymer, comprising a methacrylate and/or an acrylate, and a polymer AB which is a graft copolymer comprising a polymer A and a polymer B, wherein the amount of polymer A is from 5% by weight to 60% by weight, the amount of polymer B is from 5% by weight to 70% by weight, the amount of polymer AB is from 5% by weight to 60% by weight, based on the total weight of the polymer A, B and AB, and wherein the ratio by weight of the entirety of the polymer A, B and AB to the weight of a solvent or of a solvent mixture L is from 5:1 to 1:5.
