Abstract

Strongly adhering aqueous plastic dispersions based on copolymers of olefinically unsaturated compounds, which are particularly suitable as binding agents for paints and lacquers and as adhesives, and which are distinguished by their good wet adhesion are described. This is achieved by the inclusion by polymerization of from 0.2% to 7% by weight, based on the total weight of the monomers, of vinyl and/or allyl diacetylacetate having the formula: EQU CH.sub.2 .dbd.CH--(CH.sub.2).sub.n --O--CO--CH(CO--CH.sub.3).sub.2 wherein n is 0 or 1, in the production of copolymers of the invention in an aqueous emulsion.
