    Abstract: Compositions which can be crosslinked under an atmospheric oxygen atmosphere by means of ultraviolet irradiation and are based on (meth)acrylate copolymers having a K value of from 10 to 100, obtained by free-radical polymerisation in solid phase or solution of a) 5 to 97.4% by weight of i-amyl acrylate and/or i-amyl methacrylate and b) 0 to 89.9% by weight of (meth)acrylates whose hompolymers have a glass transition temperature of below -30 DEG C, c) 2.5 to 30% by weight of alpha , beta -monoolefinically unsaturated compounds whose homopolymers have a glass transition temperature of above - 30 DEG C, d) 0 to 10% by weight of monoolefinically unsaturated acids and/or anhydrides thereof, e) 0 to 20% by weight of further olefinically unsaturated monomers containing at least one of the following functional groups: hydroxyl, amide, epoxide, ether, ester, urethane, urea, primary, secondary or tertiary amine and ether, and f) 0.1 to 5% by weight of a copolymerisable benzophenone or acetophenone derivative, the sum of the percentages by weight x = a + b + c + d + f in each case being 100.

    Abstract: An aqueous polymer dispersion having a solids volume concentration of 50% by volume or more, obtained by free-radical aqueous emulsion polymerisation of free-radical-polymerisable monomers other than vinyl and vinylidine halides, with addition of an aqueous starting polymer dispersion having a certain diameter distribution of the starting polymer particles present therein, by the feed process.
