Abstract

Aqueous polymer latexes of film-forming copolymers obtainable by aqueous emulsion polymerisation of at least one non-ionic monomer M1; and The present invention also relates to a process for producing such polymer latexes and to the use of these polymer latexes as binders in waterborne coating compositions which contain at least one inorganic tannin blocking compound and to the use of such coating compositions for coating tannin-containing substrates such as wood or wood-based materials.
