    Abstract: A process for the production of coatings based on reaction products of (A) polyhydroxy polyacrylate resins obtained from hydroxyalkyl esters of acrylic acid and/or methacrylic acid, alkyl acrylates and/or methacrylates, one or more polymerizable, olefinically unsaturated N-containing heterocyclic compounds and if appropriate vinyl-aromatics, acrylamides or methacrylamides and other monomers with (B) isocyanurate-containing polyisocyanates having a functionality of from 2.5 to 6 and predominantly containing cycloaliphatically bonded isocyanate groups is particularly useful for coating metal articles.

    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: 1,161,095. Coatings. BADISCHE ANILIN- & SODA-FABRIK A.G. 25 Oct., 1966 [26 Oct., 1965], No. 47815/66. Heading B2K. [Also in Divisions C3, D1 and D2] Hardboard is coated with an organic solvent solution, containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate, styrene, 2-ethylhexyl acrylate, N-butoxymethylmethacrylamide, and acrylic acid, the coating then being dried and hardened by heating. An aqueous dispersion containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate with styrene may be applied to hardboard. Steel and glass sheets are coated may be with an organic solvent solution containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate, 2-ethylhexyl acrylate and styrene.

    Abstract: A composition comprises a copolymer containing N-hydroxymethyl groups in free or etherified form and an acid cure catalyst which is a mixture of one or more acids having a dissociation constant of more than 10-2 and one or more acids having a dissociation constant of 10-5 to 10-2. The amides are preferably acrylamide and methacrylamide and the etherifying alcohols are preferably C1-C8 alcohols, C2-C6 b -alkoxy ethanols or benzyl alcohol. The stronger acid may be perchloric acid, hydrogen bromide, hydrogen chloride, p-toluenesulphonic acid, or pyrophosphonic acid. The weaker acid may be formic or acetic acid. The exemplified polymer is a copolymer of the n-butyl ether of N - hydroxymethyl - methacrylamide, acrylic acid, butanediol monoacrylate, styrene and 2-ethylhexyl acrylate. The compositions are suitable for coating, moulding, impregnating and laminating and may contain solvents and pigments.ALSO:Steel sheet is sprayed with a solution comprising a copolymer containing N-methylol groups in free or etherified form and an acid cure catalyst which comprises a mixture of (1) an acid having a dissociation constant greater than 10-2 and (2) an acid having a dissociation constant between 10-5 and 10-2. Acids (1) are perchloric acid, hydrogen bromide, hydrogen chloride, p-toluenesulphonic acid, and pyrophosphoric acid. Acids (2) are formic or acetic acid. The exemplified polymer is a copolymer of the n-butyl ether of N-methylol methacrylamide, acrylic acid, butanediol monoacrylate, styrene and 2-ethylhexyl acrylate applied in a mixture of butanediol, toluene, xylene, and butanol. The catalyst system is a mixture of perchloric acid and acetic acid and the composition also contains titanium dioxide. The applied coating is heated to cross-link.

    Abstract: A stoving lacquer comprises at least one organic solvent and a mixture consisting of (i) at least 30 wt. per cent of an alkyd resin from (a) a C8- 20 aliphatic monocarboxylic acid; (b) a mixture of C4- 14 polycarboxylic acids, 2 to 30% being 3,6 - endoethenylenecyclohexane - 1,2,4,5-tetra-carboxylic acid; and (c) a C2- 10 polyol, and (ii) up to 70% of an "aminoplast resin." The term "aminoplast resin" is defined as including copolymers of N-alkoxymethyl amides of ethylenically unsaturated carboxylic acids as well as the conventional etherified urea or melamine-formaldehyde condensates but no specific example of the use of such copolymers is given. The lacquers may include curing catalysts, flow promoters and other binders, e.g. epoxy resins. In the example the solvent is xylene and TiO2 pigment is included.ALSO:A stoving lacquer comprises at least one organic solvent and a mixture consisting of (i) at least 30 wt. % of an alkyd resin from (a) a C8-20 aliphatic monocarboxylic acid; (b) a mixture of C4-14 polycarboxylic acids, 2 to 30% being 3,6-endoethenylenecyclohexane-1,2,4,5-tetracarboxylic acid; and (c) a C2-10 polyol, and (ii) up to 70% of an "aminoplast resin".
