    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 cross-linkable water-soluble copolymer of:-(1) 5 to 60 parts by weight of an N-methylol alkyl ether of acrylamide or methacrylamide wherein the alkyl moiety of the ether group has 8 to 18 carbon atoms; (2) 3 to 20 parts by weight of a polymerizable a ,b - ethylenically unsaturated mono- or di-carboxylic acid; and (3) 20 to 75 parts by weight of at least one other ethylenically unsaturated monomer; at least 50% of the free carboxylic groups of the copolymer being neutralized by ammonia or a nitrogenous organic base (e.g. methylamine, triethylamine, dimethylethanolamine, triethanolamine, piperidine or morpholine). Examples of monomer (1) are N - (2 - ethylhexoxymethyl) - acrylamide and N - (2 - octylhexoxymethyl) - methacrylamide. Suitable monomers (2) include crotonic, citraconic, itaconic, mesaconic, maleic, fumaric and, preferably, acrylic and methacrylic acids. Monomers (3) include styrene, esters of unsaturated carboxylic acids, vinyl esters (including versatic esters), N-substituted unsaturated amides, dienes, vinyl and vinylidene chloride, vinyl ethyl ketone, vinyl ethyl ether, acrylo-methacrylo-nitriles, acrylamide and methacrylamide, N-vinyl pyrrolidone, N-vinyl caprolactam, monoesters of polyhydric alcohols and unsaturated carboxylic acids, monovinyl ethers of polyhydric alcohols, allyl alcohol and bicycloheptene compounds containing hydroxy groups. White spirit or mineral spirit gasoline fractions may be used as the oil phase of the emulsion. Pigments exemplified are red iron oxide and copper phthalocyanine. The print pastes may optionally include cross-linking or curing agents, e.g. urea-formaldehyde precondensates, melamine-formaldehyde precondensates or ammonium thiocyanate.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 cross-linkable water-soluble copolymer of:- (1) 5 to 60 parts by weight of an N-methylol alkyl ether of acrylamide or methacrylamide wherein the alkyl moiety of the ether group has 8 to 18 carbon atoms; (2) 3 to 20 parts by weight of a polymerisable a ,b -ethylenically unsaturated mono- or dicarboxylic acid; and (3) 20 to 75 parts by weight of at least one other ethylenically unsaturated monomer; at least 50% of the free carboxylic groups of the copolymer being neutralised by ammonia or a nitrogenous organic base (e.g. methylamine, triethylamine, dimethyl ethanolamine, triethanolamine, piperidine or morpholine).

    Abstract: Cellulosic fibrous material is coloured or printed with non-metallic pigments (i.e. pigments which do not behave as free metal or metal alloys) by treating the material in the absence of strongly anionic substances with a) an aqueous solution, emulsion or suspension of a salt or quaternary ammonium compound of a polymer or copolymer of a vinylinidazole and with b) an aqueous non-metallic pigment dispersion containing a cation-active nonionic or weakly anion-active dispersing agent the treatment with the non-metallic pigment being simultaneous with or subsequent to treatment with the vinylinidazole compounds.

    Abstract: Compositions for use as a finishing coat on plasticized polyvinyl chloride films comprise aqueous dispersions of a copolymer of: (A) 40 to 90% by weight of methyl methacrylate; (B) 1 to 20% by weight of an ester of a polymerizable a ,b -ethylenically unsaturated carboxylic or di-carboxylic acid with a polyhydric alcohol bearing a chlorine atom in a -position to a free hydroxyl group; and (C) up to 59% by weight of one or more other ethylenically unsaturated, polymerizable compounds, the sum of the percentages of (A), (B) and (C) totalling 100. Examples of (B) are chlorohydrin esters of acrylic, methacrylic, fumaric and maleic acids with polyhydric alcohols such as 3 - chloropropanediol - (1,2); (2,3) - dichlorobutanediol - (1,4); 3 - chlorobutanetriol-(1,2,4); (1,4) - dichlorobutanediol - (2,3); 3-chloro - 2 - methyl propanediol - (1,2) and 3 - chloro - 2 - chloromethylpropanediol - (1,2). Examples of (C) are N-methylol methacrylamide, styrene, a -methyl styrene, vinyl acetate, acrylic or methacrylic acid, acrylo- or methacrylonitrile and acrylic esters of alcohols having 1 to 18 carbon atoms. The polymers are obtained by polymerization of the monomers in aqueous dispersion, the dispersions having a polymer content of 25 to 60% by weight. The dispersion may also include thickening agents such as vinylpyrrolidone-vinyl propionate copolymers; precondensates of formaldehyde with urea or melamine, e.g. dimethylol propyleneurea, dimethylolethylenurea, N,N1,N11, N111 - tetramethylolglyoxaldiureine, N,N1-dimethylol - glyoxalmonoureine or N,N1-dimethylolurea etherified with methanol; wetting agents such as sodium isopropylisohexyl-naphthalene sulphonate and buffers, e.g. an aqueous solution of NaHCO3 or NH4Cl.ALSO:Finishing coats on plasticised polyvinyl chloride films are produced by applying an aqueous dispersion of a copolymer of: (A) 40 to 90% by weight of methyl methacrylate (B) 1 to 20% by weight of an ester of a polymerizable a ,b -ethylenically unsaturated carboxylic or dicarboxylic acid with a polyhydric alcohol bearing a chlorine atom in a -position to a free hydroxyl group, and (C) up to 59% by weight of one or more other ethylenically unsaturated, polymerizable compounds, the sum of the percentages (A), (B) and (C) totalling 100, and drying the coating. Examples of (B) are chlorohydrin esters of acrylic, methacrylic, fumaric and maleic acids with polyhydric alcohols such as 3-chloropropanediol-(1,2), (2,3)-dichlorobutanediol-(1,4) 3-chlorobutanetriol-(1,2,4), (1,4)-dichlorobutanediol-(2,3), 3-chloro-2-methyl propanediol-(1,2) and 3-chloro-2-chloromethylpropanediol. Examples of C are acrylic or methacrylic acid, acrylo- or methacrylonitrile, acrylic esters of alcohols having 1 to 18 carbon atoms, n-methylol methacrylamide, styrene, a -methyl styrene, vinyl acetate. Thickening agents may be added to the dispersion which may be applied as a paste by a coating knife. Examples disclose vinylpyrrolidone copolymers as thickening agents. Precondensates of formaldehyde with urea or melamine may be added to the dispersion such as aminoplasts, e.g. dimethylolpropylenurea, dimethylolethylenurea, N, N\sv, N\yF, N\yG-tetramethylol glyoxaldiureine, N, N\sv-dimethylol-glyoxalmonoureine or N, N\sv-dimethylolurea etherified with methanol. In some of the Examples the plasticized polyvinyl chloride is in the form of a coating on a substrate such as cloth and is pregelled at 120 DEG to 130 DEG C, the finishing coat then spread on and gelling completed at 170 DEG to 180 DEG C, and finally embossed. A wetting agent is present in the aqueous dispersion in some cases.

    Abstract: Glass fibres are dyed or printed with pigments using as a binder a film-forming polymer which becomes cross-linked under the influence of a proton-acceptor and using an amino-silane or a hydrocarbon wax as an agent having hydrophobic action to promote adhesion between the binder and the glass surface, the process being carried out in the presence of a proton-acceptor, and the treated fibres being finally dried and heated. The polymers are those having groups, for example amino or hydroxy groups, which by means of proton acceptors can enter into covalent bonds with themselves or other groups. The preferred polymers are copolymers bearing hydrocarbon radicals as side chains in which a halogen atom and a hydroxyl group are attached to two adjacent carbon atoms, particularly a polymer obtained by co-polymerising 2-hydroxy-3-chloropropyl acrylate with other monomers. The proton-acceptor may be an alkali metal hydroxide, carbonate or bicarbonate, amonia or an organic amine; it may be provided as the alkali present in the glass. The glass fibres may be treated as such, mixed with other fibres or in the form of fabric. In the treatment, the various components can be applied separately or in combination. Examples illustrate the use of copper phthalocyanine, azo dyes and carbon black as the pigments.
