    Abstract: Aqueous polymer dispersions based on (A) 1 to 99% by weight of a carboxy-functional polymer which additionally contains epoxy groups, (B) 1 to 99% by weight of a polymer obtained from at least one alpha , beta -olefinically unsaturated monomer, the polymer (B) having been prepared in the presence of polymer (A), (C) 0 to 20% by weight of anionic or non-ionic emulsifiers or a mixture of the two or protective colloids, the quantity data relating to the solids content of components (A) to (C), and if appropriate further conventional additives, the sum of all the components always being 100%. The invention also relates to a process for the preparation of such polymer dispersions, which are particularly suitable as a binder component in metallic basecoats or metal-free, (uni) basecoats and electrocoatings.

    Abstract: The aq. dispersion contains, as binder, a crosslinkable dispersion copolymer of olefinically unsatd. monomers and opt. further standard constituents of lacquer compsns. The dispersed copolymers have average particle size 0.5-10 mu. The novelty consists in that the proportion of crosslinkable gp.-bearing comonomer units in the dispersion copolymer is over 10 (11-25) wt.% w.r.t. the copolymer. The dispersion copolymer is prepd. by emulsion- or suspension copolymerisation with the addn. of radical chain transfer agents, esp. cpds. contg. mercapto gps. The aq. dispersion is useful as a constituent of stoving lacquers, hydro-fillers, metallic lacquers and electropowder coatings.

    Abstract: Polyurethane dispersions based on reaction products from (A) bismethylolated urethanes having at least 2 urethane groups and (B) polyhydroxyl compounds which contain groups which are capable of ion formation, these groups being present in neutralized form, and a process for the preparation thereof. The use of the dispersions for the surface-coating of metal, plastics, glass, leather and paper.
