ABSTRACT:
The invention relates to new, aqueous secondary copolymer dispersions, to a process for preparing them and to their use for producing high-grade coatings, especially for wood. The dispersions comprise a copolymer (P) synthesized from a mixture of free-radically polymerizable monomers (M) comprising (M1) cycloaliphatic esters of acrylic and/or methylacrylic acid and also (M2) vinyl esters of aliphatic carboxylic acids.
