    Abstract: Emulsion copolymers obtainable by copolymerization in the emulsion of (a) a dye which contains a polymerizable olefinic double bond, (b) one or more non-coloured compounds which contain polymerizable olefinic double bonds and groups accessible to cross-linking by addition or condensation and, optionally, (c) one or more polymerizable non-coloured compounds (inert to cross-linking) used for the production of plastics are employed for simultaneously dyeing and finishing textiles and are subsequently cross-linked either alone or with the aid of (d) suitable bi- or polyfunctional compounds, either by condensation or addition. The chromophoric monomers (a) may be based on dyes of the azo, anthraquinone, triarylmethane, phthalocyanine, phenazine and oxazine series (see Group IV(c)). While many components (b) and (c) are specified those mentioned in the examples are (b) N-methylolmethacrylamide, N-methylol-acryloylurea, N-methylol-N-acryloylmaleic acid imide, butanediol monoacrylate, methacrylamide, acrylic acid and 2:4-diamino-6-acryloylaminoethylene-1:3:5-triazine and (c) ethyl acrylate, butyl acrylate, methyl methacrylate, acrylonitrile, styrene, vinyl propionate and vinyl chloride. The copolymers, whose solid content is preferably 25-50%, may be prepared in the presence of polymerization initiators such as hydrogen peroxide and potassium persulphate. Cross-linking may be effected by heating or changing the pH with or without the aid of many specified components (d) and other catalysts. The components (d) mentioned in the examples are the bisulphite compounds of hexamethylene di-isocyanate and toluylene di-isocyanate, N,N1-dimethylolurea and its methyl ethers, the N,N1-dimethylolated diurethane of butane-diol-(1,4), the reaction product of pentaerythritol and epichlorhydrin and an etherified urea-formaldehyde resin precondensate. Examples are given of the preparation of copolymers and their employment in dyeing and printing fabrics.ALSO:Textiles are simultaneously dyed and finished by treating with emulsion copolymers obtainable by copolymerization in the emulsion of (a) a dye which contains a polymerizable olefinic double bond, (b) one or more non-coloured compounds which contain polymerizable olefinic double bonds and groups accessible to cross-linking by addition or condensation and, optionally, (c) one or more polymerizable non-coloured compounds (inert to cross-linking) used for the production of plastics, and subsequently crosslinking the copolymer either alone or with the aid of (d) suitable bi- or polyfunctional compounds, either by condensation or addition. The chromophoric monomers (a) may be based on dyes of the azo, anthraquinone, triarylmethane, phthalocyanine, phenazine and oxazine series; suitable dyes are described in Specifications 830,876, 858,183, 875,946, 877,402 and 879,071, German Specification 1,010,063 and French Specification 1,118,705. Many components (b) are specified, among which are N-methylolmethacrylamide, N-methylol-N-acryloylmaleic acid imide, butanediol monoacrylate, methacrylamide and acrylic acid; many components (c) are also specified, those mentioned in the examples being ethyl acrylate, butyl acrylate, methyl methacrylate, acrylonitrile, styrene, vinyl propionate and vinyl chloride. The copolymer emulsions, whose solid content is preferably 25-50%, may also contain the usual emulsifiers and protective colloids, as well as a thickener, when the copolymer is used as a printing paste. Cross-linking may be effected by heating or changing the pH with or without the aid of many specified components (d) and other catalysts. Examples are given of the preparation of copolymers and the dyeing and printing of fabrics of cotton (woven and non-woven), rayon staple, calico and regenerated cellulose. Other specified materials are of wool, silk, polyamide, cellulose acetate, polyvinyl alcohol and polymers and copolymers of acrylonitrile.

    Abstract: 1,203,427. Coatings. BADISCHE ANILIN- & SODA-FABRIK A.G. 1 Dec., 1967 [3 Dec., 1966], No. 54719/67. Heading B2E. [Also in Division C3] Substrates, such as textiles, paper, leather, wood, metals, glass, ceramics and concrete, are coated with compositions comprising (I) a crosslinkable copolymer dispersion prepared by copolymerising (a) an olefinically unsaturated compound containing a hydroxyl group and (b) at least one olefinically unsaturated comonomer in (c) an organic liquid in which the copolymer of (a) and (b) is substantially insoluble and which is inert to organic isocyanate groups, and in the presence of (d) a copolymer of monomers of group (a) and group (b), which is soluble in (c); and (II) a diisocyanate or polyisocyanate. Suitable monomers (a) include unsaturated alcohols, N- methylol amides or mono- or di-ethanolamides of acrylic or methacrylic acid, and hydroxyalkyl esters of acrylic, methacrylic or maleic acid. Specified as monomer (b) are butadiene, styrene, vinyl chloride, vinylidene chloride, acrylonitrile, methacrylonitrile, C 1 -C 12 alkyl esters of acrylic, methacrylic or maleic acid, vinyl esters of C 2 -C 24 alkanoic acids, acrylic, methacrylic or maleic acid, maleic anhydride, acrylamide, methacrylamide, N-vinylimidazole and N-vinyl-imidazolium methyl sulphate. Suitable as the organic liquid (c) are aliphatic, cycloaliphatic or aromatic hydrocarbons, terpenes, aliphatic ketones, ethers and esters, chlorinated hydrocarbons, cyclic ethers, dimethyl sulphoxide, dimethylformamide and acetonitrile. Component (II) may be an aliphatic, cycloaliphatic, araliphatic or aromatic di- or tri-isocyanate. Additives such as levelling agents, anti-corrosives, matting agents, crosslinking catalysts, pigments and silicone resins may be included in the copolymer dispersions. The coatings produced can be crosslinked by heating to 60-160‹C and/or by means of a catalyst. An Example illustrates the application of a copolymer dispersion to nylon 6 cloth in a coating thickness of 15g/sq.m.
