ABSTRACT:
An aqueous polymer emulsion is obtained by polymerizing first a monomer composition 1 in a first polymerization stage and then a monomer composition 2 in a polymerization stage 2, in each case by the free radical aqueous emulsion polymerization method, one of the two monomer compositions essentially comprising hard monomers and the other monomer composition essentially comprising soft monomers, and, in addition to the monomer compositions 1 and 2, nitrogen-containing adhesion-promoting monomers being polymerized, at least 20 mol % of the total amount of the adhesion-promoting monomers being polymerized in polymerization stage 1.
