Aqueous synthetic resin composition

An aqueous synthetic resin formulation, essentially containing
A) from 3 to 75% by weight of one or more synthetic resins which are composed of a) from 50 to 99.9% by weight of one or more esters of ,ß-monoethylenically unsaturated carboxylic acids of 3 to 6 carbon atoms and alkanols of 1 to 18 carbon atoms or one or more vinyl esters of an aliphatic monocarboxylic acid of 2 to 8 carbon atoms or of a mixture of these monomers (monomers a), b) from 0.1 to 12% by weight of one or more ,ß-monoethylenically unsaturated monobasic or dibasic acids of 3 to 8 carbon atoms, of their anhydrides or of a mixture of these monomers (monomers b), c) from 0 to 10% by weight of one or more monoethylenically unsaturated acetophenone or benzophenone derivatives or of a mixture of these monomers (monomers c) and d) from 0 to 35% by weight of one or more other copolymerizable monoethylenically unsaturated monomers (monomers d), in polymerized form,
the weights of monomers a, b and d being chosen within the stated limits in such a way that a synthetic resin consisting only of these monomers would have a glass transition temperature of from 40 to -50°C, B) one or more metal cations having a charge of from 2 to 4, in water-soluble form, C) from 0 to 10% by weight, based on the synthetic resin A, of benzophenone or acetophenone or of one or more acetophenone or benzophenone derivatives which are not monoethylenically unsaturated or of a mixture of these active ingredients, D) effective amounts of emulsifiers or protective colloids or a mixture of these active ingredients, E) not less than 5% by weight of water and F) from 0 to 85% by weight of finely divided fillers,
with the proviso that the total amount of the monomers c and of component C is from 0.05 to 10% by weight, based on the synthetic resin A, and the total amount of the cations B is such that it is capable of neutralizing from 0.2 to 6 times the amount, corresponding to the amount of acid functions incorporated in the form of the monomers b in the synthetic resin A, of their conjugated bases.
