摘要:
The invention describes a composition comprising, in the form of aqueous dispersion, A) for every 100 parts by weight of a, or of a plurality of, (meth)acrylate polymer(s); B) from 1-400 parts by weight of a, or of a plurality of, (meth)acrylate polymer(s), which contain(s) a compound of the formula (I) copolymerized, where the (meth)acrylate polymer(s) B) differ from the (meth)acrylate polymers specified in A), where these are obtainable by emulsion polymerization of a mixture comprising a) from 0.1 to 99.9 percent by weight of at least one compound of the formula (I), preferably of a benzophenone (meth)acrylate, in which the definitions of the moieties are those given in the description; and b) from 99.9 to 0.1% by weight of a, or of a plurality of, ethylenically unsaturated monomer(s) which differ(s) from a) and which is/are copolymerizable with a), where components a) and b) together give 100% by weight of the polymerizable constituents of the mixture; and where the parts by weight of A) and B) are based on the solids content of the polymers A) or B) in the aqueous dispersion. Dispersions of this type are UV-curable and have excellent suitability for the production of coatings of any type, in particular for coating of mineral substrates, such as concrete. The dispersions of the invention are also advantageous for blending with known dispersions and improve their properties, in particular in respect of their curing profile.
