    Abstract: Print pastes for textiles and other substrates comprise an oil-in-water emulsion containing a pigment or vat dye and, as a binder, a water-soluble copolymer of:-(1) to 70 parts by weight of a neutral ester of an a , b -ethylenically unsaturated mono-or di-carboxylic acid and an aliphatic or cycloaliphatic alcohol having at least 6 carbon atoms; (2) 1 to 40 parts by weight of an ethylenically unsaturated polymerizable nitrogenous compound containing at least one N-methylol ether group; (3) 4 to 15 parts by weight of a polymerizable a , b -ethylenically unsaturated mono- or di-carboxylic acid; (4) 0 to 20 parts by weight of an ethylenically unsaturated polymerizable hydroxy compound; and (5) 0 to 70 parts by weight of another ethylenically unsaturated monomer; the total amount or major proportion of the free carboxylic groups in the copolymer having been neutralized by ammonia or a nitrogenous organic base (e.g. methylamine, triethylamine, dimethy-ethanol-amine, triethanolamine, piperidine or morpholine). Suitble monomer components of the copolymer include (1) esters of acrylic, methacrylic, crotonic, maleic or fumaric acid with hexanol, heptanol, octanol, isooctanol, dodecanol, a -ethylhexanol, cyclohexanol or hexanediol; (2) N-methylol ethers of unsaturated amides and imides and unsaturated compounds containing a ureido, aminotriazine, dicyanodiamide, carbamic acid, thiocarbamic acid; glyoxal-monoureine or glyoxal diureine group; (3) crotonic, citraconic, itaconic, mesaconic, maleic, fumaric and, preferably, acrylic or methacrylic acid; (4) monoesters of polyhydric alcohols and ethylenically unsaturated carboxylic acids, monovinyl ethers of polyhydric alcohols, allyl alcohol and hydroxy-containing bicycloheptene derivatives; (5) styrene, esters of acrylic or methacrylic acid with alcohols having up to 5 carbon atoms, vinyl esters (including versatic esters), butadiene, isoprene, acrylonitrile, methacrylonitrile, acrylamide and methacrylamide and their N-alkyl derivatives, vinyl chloride, vinylidene chloride, vinyl ethyl ether, vinyl ethyl ketone, N-vinylimidazole, N-vinyl pyrrolidone and N-vinyl caprolactam. White spirit or mineral spirit gasoline fractions may be used as the oil phase of the emulsion. Pigments exemplified are red iron oxide, aluminium poweder and copper phthalocyanine. The print pastes may optionally include cross-linking or curing agents such as aminoplasts and ammonium thiocyanate. In an example the binder comprises a copolymer of a -ethylhexyl acrylate, N-(n-butoxymethyl)-acrylamide, acrylic acid, 1, 4-butanediol monoacrylate and styrene, neutralized with dimethylethanolamine.ALSO:Print pastes for textiles, e.g. cotton cloth, and other substrates comprise an oil-in-water emulsion containing a pigment or vat dye and, as a binder, a water-soluble copolymer of:- (1) 10 to 70 parts by weight of a neutral ester of an a ,b -ethylenically unsaturated mono- or dicarboxylic acid and an aliphatic or cycloaliphatic alcohol having at least 6 carbon atoms; (2) 1 to 40 parts by weight of an ethylenically unsaturated polymerisable nitrogenous compound containing at least one N-methylol ether group; (3) 4 to 15 parts by weight of a polymerisable a ,b -ethylenically unsaturated mono- or di-carboxylic acid; (4) 0 to 20 parts by weight of an ethylenically unsaturated polymerisable hydroxy compound; and (5) 0 to 70 parts by weight of another ethylenically unsaturated monomer; the total amount or major proportion of the free carboxylic groups in the copolymer having been neutralised by ammonia or a nitrogenous organic base (e.g. methylamine, triethylamine, dimethyl ethanolamine, triethanolamine, piperidine or morpholine). White spirit or mineral spirit gasoline fractions may be used as the oil phase of the emulsion. Pigments exemplified are red iron oxide, aluminium powder and copper phthalocyanine. The print pastes may optionally include cross-linking or curing agents such as aminoplasts and ammonium thiocyanate. In an Example the binder comprises a copolymer of a -ethylhexyl acrylate, N-(n-butoxymethyl)-acrylamide, acrylic acid, 1,4-butanediol monoacrylate and styrene, neutralised with dimethylethanolamine.

    Abstract: A composition suitable for treating cellulosic fabrics comprises a compound which improves the crease resistance of the fabric and a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0.5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N-methylolmethacrylamide or an ether derivative thereof and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5 - triacyl - hexahydrotriazine - (1,3,5) allyl acrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinyl-pyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diureine, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetal, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The composition may be in the form of an aqueous solution or dispersion containing 30-150 g./l. of the crease-resisting agent and 5-100 g./l. of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants, colouring pigments and an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, mono-ammonium phosphate, ammonium nitrate and ammonium acetate. ALSO: The tendency of crease proofed cellulosic fabrics to become irreversibly soiled during washing with hot aqueous liquids is reduced by effecting the crease-proofing by a process comprising treating them with a compound which improves the crease resistance of the fabric and with a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0.5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N-methylolmethacrylamide and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane, diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5- triacryl-hexahydrotriazine- (1, 3, 5) allylacrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinylpyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diurein, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetol, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The crease resisting agent and copolymer may be applied from an aqueous solution or dispersion containing 30-150 g/1 of the crease resisting agent and 5-100 g/1 of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants or colouring pigments. Alternatively the crease resisting agent and the copolymer may be applied successively in any sequence. The treating agents may be fixed on the fabrics by the action of an elevated temperature and/or an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, monoammonium phosphate ammonium nitrate and ammonium acetate. After impregnation and prior to heating the fabric may be calendered on a Schreiner calender. Fabrics comprising cotton, linen, or viscose rayon fibres alone or in admixture with polyamide, polyester, cellulose ester or acrylonitrile polymer fibres may be treated.
