Abstract:
1. An aqueous composition comprising a) a polymer having a Tg of from −60 to 0° C. obtainable by free-radical polymerization wherein the polymer comprises at least 40% by weight of main reacted monomers selected from the group consisting of C1 to C20 alkyl (meth)acrylates, vinyl esters of carboxylic acids comprising up to 20 carbon atoms, vinylaromatics having up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl halides, vinyl ethers of alcohols comprising from 1 to 10 carbon atoms, aliphatic hydrocarbons having from 2 to 8 carbon atoms and one or two double bonds, and mixtures of these monomers b) 10 to 300 parts by weight per 100 parts by weight of polymer of a tricyclic diterpene derivative comprising abietic acid; and c) 0.005 to 10 parts by weight per 100 parts by weight of diterpene of a metal salt of an organic acid wherein said metal is manganese, and d) 10 to 400 parts by weight per 100 parts by weight of polymer of a filler wherein said polymer is used in the form of an aqueous dispersion and said composition has a solids content of from 50 to 95% by weight.
