    Abstract: A water-soluble addition copolymer of: (a) a dye containing in the molecule a polymerizable group which is not part of the chromophoric group in the molecule, (b) a water-soluble comonomer containing in the molecule at least once the grouping may be used for the temporary dyeing of textile fibres (see Division D1). The copolymer may also contain (c) a water-insoluble comonomer. The comonomer dye (a) may be an azo dye or anthraquinone dye which contains in the molecule a vinyl group which is not part of the chromophoric group in the molecule. The water-soluble comonomer (b) may be an a ,b -unsaturated carboxylic acid, e.g. acrylic, methacrylic, maleic or fumaric acid, or an alkali metal salt, ammonium salt or amide thereof. The water-soluble comonomer (b) may also be an N-vinyllactam such as N-vinylpyrrolidone, or 2-aminoethyl acrylate and its salts. The water-insoluble comonomer (c) may be an ester of acrylic, methacrylic, maleic or fumaric acid, acrylonitrile, a vinyl ester, vinyl or vinylidene chloride, styrene, butadiene, ethylene or propylene.ALSO:Textile fibres in the form of filaments, staple fibres, yarns, woven fabrics &c., are temporarily dyed for identification purposes during manufacture by means of a water-soluble addition copolymer of (a), a dye containing in the molecule a polymerizable group not forming part of its chromophoric group or system in the molecule (b), a water-soluble comonomer containing in the molecule at least one group The copolymer may also contain (c) a water-in-soluble comonomer. The dye (a) may be an azo dye or an anthra-quinone dye which contains in the molecule a vinyl group which is not part of the chromophoric group or system in the molecule. The comonomer (b) may be an alpha, beta unsaturated carboxylic acid or an alkali metal salt, ammonium salt or amide thereof. The comonomer (b) may be an N-vinylpyrrolidone. The dye may be applied to the textile fibre material in the form of a dilute aqueous solution and after having served its identification purpose during subsequent processing of the material is readily washed out of the processed textile material with plain water or hot water which has been rendered weakly alkaline. The water-insoluble comonomer (c) may be ethyl acrylate or methyl methacrylate.

    Abstract: Leather is simultaneously dyed and finished using a coloured polymer in which the dye is bound to the polymer by a covalent bond. The polymer may be obtained by copolymerizing a dye bearing at least one polymerizable olefinically unsaturated group with one or more polymerizable monomers (many listed) or the polymer may be one on to which a copolymerizable dye has been grafted or the polymer may be attached to the dye by way of reactive groups both on the polymer and the dye. The polymers may be in solution or dispersion, preferably aqueous dispersion. The coloured polymers may contain reactive groups, e.g. by using N-methylolacryl- or methacrylamide as a comonomer, through which cross-linking may be effected. The coloured polymers may be applied by brushing, dipping or spraying or in a drum. The so-treated leather may afterwards be glazed or plated. Examples are given. Specifications 877,402, 914,282, 946,472, 964,757 and 965,627 are referred to.

    Abstract: Stable compositions suitable for finishing textiles comprise a mixture of polyacrylamide and an aqueous dispersion of a water-repelling agent based on a zirconium salt, an aluminium salt and/or a solid paraffin, the polyacrylamide having been prepared by polymerizing acrylamide, optionally together with not more than 1% by weight (based on the polymer) of a comonomer such as a carboxylic monomer, in the presence of a free radical catalyst and a mercaptan having an O-containing group adjacent to the -SH group. Salts specified are zirconium acetate and aluminium oxychloride. The compositions may also contain additives such as white oil, bone glue, buffers, acetic acid, and condensation products of formaldehyde with ureas, melamine, dicyanodiamide and etherified derivatives thereof. The polyacrylamide is preferably prepared in aqueous solution at a pH of from 3.5 to 6 using a catalyst such as hydrogen peroxide, acetyl peroxide or azodiisobutyronitrile, or less preferably a persulphate or perborate, and an oxygen-containing mercaptan such as 2-mercapto-ethanol, 1 - thio - glycerine or thioglycollic acid. The reaction mixture may also include a small amount of K2FeCl4. Textiles treated with the compositions are finished by heating the impregnation, optionally in the presence of a curing catalyst such as ammonium chloride.ALSO:Textiles are finished by impregnating with a composition comprising polyacrylamide and an aqueous dispersion of a water-repelling agent based on a zirconium salt (e.g. the acetate), an aluminium salt (e.g. the oxychloride and/or a solid paraffin, the polyacrylamide having been prepared by polymerising the monomer in the presence of a free radical catalyst and a mercaptan having an O-containing group adjacent to the -SH group. The compositions may optionally include additives such as white oil, bone glue, buffers, acetic acid, ammonium chloride (curing catalyst) and aminoplast condensation products. The impregnated textiles are dried and heated to obtain water-repellent and, optionally, crease-proof, swelling-proof and shrink-resistant finishes. The compositions can be applied to woollen, cotton and synthetic-fibre fabrics.
