Aqueous polymer dispersions which are suitable for the preparation of paints having high wet adhesion are prepared by copolymerisation in an aqueous medium of a curing component and a plasticising component, and of acrylic acid, methacrylic acid, acrylamide and/or methacrylamide. The copolymerisation is additionally carried out in the presence of a compound of the formula <IMAGE> in which X is -O-, -O-CH2- or <IMAGE>, and R and R' are hydrogen or methyl, or the acetoacetic ester of hydroxypropyl acrylate or methacrylate. |
