摘要： Baking finishes having a high solids content contain, as the binder, a copolymer of one or more mono-acrylate or monomethacrylate of an alkanediol, an ester of acrylic or methacrylic acid whose homopolymer has a glass transition temperature of below -40.degree. C., an ester of acrylic acid or methacrylic acid whose homopolymer has a glass transition temperature of above 35.degree. C. and acrylic acid or methacrylic acid, which copolymer has a Fikentscher K value of from 13 to 17 and may or may not be used in combination with conventional aminoplast precondensates having a crosslinking action. These baking finishes are particularly useful as binders for automotive finishes.

摘要： Surface-coating binders based on a copolymer which contains tertiary amino groups, blocked isocyanate groups, hydroxyl groups and ether groups and which, due to partial or complete salification with an acid, is water-soluble or water-dispersible.This copolymer contains, as copolymerized units, one or more olefinically unsaturated compounds possessing a tertiary amino group, an N-(1-alkenyl) isocyanate blocked with a CH--, OH-- or NH-acidic blocking agent, an adduct of an epoxy resin based on bisphenol A and epichlorohydrin, and having a molecular weight of from 380 to 3,500, with an olefinically unsaturated alcohol of 3 to 20 carbon atoms, and one or more other copolymerizable olefinically unsaturated compounds, and has a mean molecular weight of from 1,000 to 20,000.The novel surface-coating binder is used for the cathodic electrocoating of metallic articles.
