    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: Surface coating binders which contain tertiary amino groups, blocked isocyanate groups, hydroxyl groups and ether groups and are water-soluble or water-dispersible as a result of partial or complete salt formation with an acid are prepared by copolymerization of a mixture comprising (A) an olefinically unsaturated compound which contains a tertiary amino group, (B) an N-(1-alkenyl)-isocyanate which is blocked with a CH-, OH- or NH-acidic blocking agent and (C) an adduct of an epoxy resin based on bisphenol A and epichlorohydrin, and an olefinically unsaturated carboxylic acid of 3 to 20 carbon atoms, a secondary amine and, if required, a saturated monocarboxylic acid of 1 to 20 carbon atoms, with or without one or more copolymerizable, olefinically unsaturated compounds not mentioned under (A), (B) and (C). These surface coating binders are particularly useful as self-crosslinking or externally crosslinking binders for the cathodic electrocoating of metal articles.

    Abstract: Surface-coating binders based on a copolymer which contains tertiary amino groups and blocked isocyanate groups and is water-soluble or water-dispersible as a result of being at least partially salified with an acid. The copolymer contains, as copolymerized units, an olefinically unsaturated compound which possesses a tertiary amino group, an N-(1-alkenyl)-isocyanate which is blocked with a CH-, OH- or NH-acidic blocking agent, and another olefinically unsaturated compound, with or without one or more copolymerizable olefinically unsaturated compounds which possess hydrogen atoms which are reactive toward isocyanate groups, and has a mean molecular weight of from 1,000 to 20,000. The novel surface-coating binders are used for the cathodic electrocoating of metallic articles.
