    Abstract: A process for the production of coatings based on reaction products of (A) polyhydroxypolyacrylate resins obtained from hydroxyalkyl esters of acrylic acid and/or methacrylic acid, alkyl esters of acrylic acid and/or methacrylic acid, and one or more polymerizable, olefinically unsaturated nitrogen-containing heterocyclic compounds, with or without vinylaromatics, (meth)acrylamides and other monomers, with (B) isocyanurate-containing polyisocyanates which may or may not contain biuret groups, have a functionality of from 2.5 to 6 and consist of a mixture of polyisocyanates possessing predominantly cycloaliphatically bonded isocyanate groups with those possessing predominantly aliphatically bonded isocyanate groups. The process is particularly useful for coating metal components.

    Abstract: The invention relates to the use of an isocyanate group-containing copolymer of from 5 to 60% by weight of an N-(1-alkenyl) isocyanate and from 95 to 40% by weight of at least one (meth)acrylate, some of which may be replaced by further copolymerisable, olefinically unsaturated compounds containing no OH-, CH-, NH- or SH-acidic groups, the copolymer having a mean molecular weight of from 500 to 10000, in combination with low-molecular-weight diols and/or polyols as a binder for polyurethane paints, in particular for automotive refinish paints.

    Abstract: Nonaqueous polymer dispersions are obtainable by polymerization of esters (A) of acrylic acid and/or methacrylic acid and/or ethylacrylic acid with C1-C20-alcohols in an organic solvent or a mixture of organic solvents in which the polymers formed are insoluble, and in the presence of copolymers (B) having a molecular weight of from 500 to 20,000 and obtainable by bulk or solution polymerization of monoolefinically unsaturated monomers at from 180 DEG to 400 DEG C. and from 1 to 200 bar, and the said dispersions are used for the production of finishes, coating materials and adhesives.
