    Abstract: 1,198,149. Print pastes; copolymer dispersions. BADISCHE ANILIN- & SODAFABRIK. 23 Dec., 1967 [24 Nov., 1966], No. 53302/67. Heading C3P. [Also in Division D1] An aqueous print paste comprises a pigment (e.g. iron oxide), and as binder a copolymer dispersion which has been prepared by free-radical copolymerization of:-(a) a monomer containing in the molecule at least one N-methylol group or an N-alkoxymethyl group and from 99-70% by weight [with reference to (a) plus (b)] of (b) a comonomer which does not contain any of the groups specified under (a) in the presence of (c) an organic liquid in which the copolymer formed is substantially insoluble and also in the presence of (d) a copolymer of comonomers of groups (a) and (b) which is soluble in the organic liquid (c). Monomers defined under (a) include the N-methylolamides and N-alkoxymethylamides of acrylic and methacrylic acids, also of crotenic, itaconic, maleic and α-chloroacrylic acids and N-acryloylurea. Comonomers used in (b) may be formed from butadiene, styrene, vinyl chloride, vinylidene chloride, acrylonitrile, methacrylonitrile, and N-vinylpyrrolidine. Organic liquids include benzene, toluene, xylene, terpenes, dionone, tetrahydrofuran, ethylene chloride, acetonitrile, dimethylformamide, dimethylsulphonide and gasoline. In examples copolymers of (1) ethyl acrylate and N-methylol-methacrylamide butyl ether, (2) ethyl acrylate, acrylonitrile and N-methylolmethacrylamide butyl ether copolymer, and (3) vinyl propionate, ethyl acrylate and N-methylolmethactylamide butyl ether are prepared by copolymerization in the presence of a copolymer of styrene, ethylhexyl acrylate, N-vinylimidazole and N-methylol-methacrylamide butyl ether. The compositions may include a crosslinking component, e.g. methylolated diurethane of butanediol.

    Abstract: Coloured hair lacquers or hair setting compositions containing a coloured macromolecular substance, are formed by chemically combining a dye with the macromolecular substance or by copolymerizing the dye with a colourless monomer. The dye may be combined with the polymer through the reactive groups by means of a condensation reaction. Suitable polymers are the copolymers of acrylamide or methacrylamide with acrylic acid esters, methacrylic acid esters, vinyl esters, vinyl lactams and if desired small amounts of unsaturated carboxylic acids. Dyes suitable for this purpose are those of the azo or anthraquinone series containing N-methylol groups as reactive groups. Dyes which can be used for copolymerization are those of the azo or anthraquinone series containing in the molecule a polymerizable olefinically unsaturated group outside the chromophoric system. Suitable monomers for copolymerizing with these dyes are acrylamide, methacrylamide, a low molecular weight acrylic esters or methacrylic ester, vinylacetate, vinyl-propionate and/or a vinyl-lactam. Specification 877,402 is referred to.ALSO:Coloured hair or hair setting compositions containing a coloured macromolecular substance are formed by chemically combining a dye with the macromolecular substance or by copolymerizing the dye with a colourless monomer. The dye may be combined with the polymer through the reactive groups by means of a condensation reactive. suitable dyes are those of the azo or anthraquinone series containing N-methylol groups e.g. the coupling product of diazotized N-(p-aminophenyl)-glyoxal-diureine and 1-(p-sulfophenyl)-3-methyl pyrazoline-(5) which has been reacted with formaldehyde, the coupling product of diazotized N-(p-amino phenyl)-glyoxal-diureine and N-acetyl aminonaphthol-(1-3, 6, disulfonic acid which has been reacted with formaldehyde; the coupling product of diazotized N-p-amino phenyl urea and 4-tertiary-butyl phenol which has been reacted with formaldehyde; and 4-azophenyl acetoacetic acid anilide. Suitable dyes for copolymerization are anilide. Suitable dyes for copolymerization are those of the azo or anthraquinone series containing in the molecule a polymerizable olefinically unsaturated group outside the chromophoric system e.g. the coupling products of 1-amino-3-acryloyl aminobenzene with 1-[N-(2-hydroxyethyl)-N-(2-cyanoethyl)-amino]-3-methylbenzene, of 1-amino-4-acryloyl aminobenzene with 1-hydroxynaphthalene-4-sulfonic acid, or 2, 4-dichloroaniline with N-ethyl-N-b -vinyl oxyethylaniline, of p-aminostyrene with 1-hydroxynaphthalene-4-sulfonic acid and 1-amino 2-acetyl-4-acryloyl-aminoanthraquinone.
