Abstract

A description is given of a pressure-sensitive adhesive dispersion comprising a water-dispersed polymer P1 formed by emulsion polymerization. The polymer P1 is formed from a monomer mixture comprising (a) at least 40% by weight of C4 to C20 alkyl (meth)acrylates which when polymerized as homopolymers have a glass transition temperature of −30° C. or less, (b) at least 0.05% by weight of (meth)acrylate monomers having a substituent of the formulawhere X is CH2, O, NH or NR and R is a C1 to C4 alkyl group, (c) at least 0.1% by weight of acid monomers. The monomer mixture comprises alternatively at least 0.05% by weight of glycidyl (meth)acrylate and/or the pressure-sensitive adhesive dispersion comprises at least one further polymer P2 which contains glycidyl groups.
