    • 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.
    • 本发明描述了一种组合物,其包含水分散体的形式,A)每100重量份的一种或多种(甲基)丙烯酸酯聚合物; B)1-400重量份的一种或多种(甲基)丙烯酸酯聚合物,其含有(s)共聚的式(I)化合物,其中(甲基)丙烯酸酯聚合物( s)B)与A)中规定的(甲基)丙烯酸酯聚合物不同,其中这些可通过将混合物乳液聚合而获得,所述混合物包含a)0.1至99.9重量%的至少一种式(I)化合物,优选 的二苯甲酮(甲基)丙烯酸酯,其中部分的定义是在说明书中给出的那些; 和b)99.9重量%至0.1重量%的a)或多个不同于a)的烯键式不饱和单体,并且其可与a)共聚,其中组分a)和b) 一起提供100重量%的混合物的可聚合组分; 并且其中A)和B)的重量份数基于水分散体中聚合物A)或B)的固体含量。 这种类型的分散体是可UV固化的,并且对于任何类型的涂料的生产具有优异的适用性,特别是用于矿物基材例如混凝土的涂层。 本发明的分散体也有利于与已知的分散体共混并改进其性能,特别是在其固化分布方面。
