    Abstract: Polymeric substances are coloured by graft polymerizing thereon a dye bearing a polymerizable olefinic group and, if desired, other monomers which are colourless. Polymers specified are polymers and copolymers of olefinic monomers, polyaldehydes, polymers of lactams, lactones, cyclic ethers sulphides and amines, phenol, urea, melamine and alkyd resins, polyesters, polyamides, polycarbonates, polyurethanes, epoxy resins, cellulose, proteins and rubber. The polymerizable dyes may be of the azo, anthraquinone, triarylmethane, azomethane or phthalocyanine type. Grafting may be effected by means of a free-radical initiator or high-energy irradiation. The substrate monomer may be dissolved in the grafting monomer, or may be used in the form of a solution in an organic solvent or as an aqueous emulsion, or may be in the form of a film or fibre. The examples describe: (1) grafting by means of X-rays isobutyl 1 - amino - 4 - acryloylaminoanthraquinone - 2 - carboxylate and butyl acrylate on to an aqueous dispersion of a copolymer of butyl acrylate and methylol methacrylamide, followed by cross-linking the product with the dimethylol compound of butanediol-1, 4-diurethane; (2) as in (1), but using as the grafting monomer the coupling product of diazotized 2-amino-4-sulphonic acid-41-acryloylaminodiphenyl sulphone and 3-sulphonic acid-7-aminonaphthol-1; (3) grafting by means of X-rays the coupling product of diazotized 1-acryloylamino-4-aminobenzene and 1-phenyl-(21-chloro-41-sulphonic acid)-3-methylpyrazolone-5 on to an aqueous dispersion of a copolymer of butyl acrylate acrylonitrile and methylol methacrylamide, and cross-linking the product with the dimethylol compound of butanediol-1, 4-diurethane; (4) as in (3), but grafting by means of potassium persulphate; and (5) as in (3), but using a copolymer of butyl acrylate and methacrylamide as the grafting substrate. The resulting products are used for colouring cotton fabrics. Specifications 877,402, 914,354, 946,472, 948,694, and 952,810 are referred to.ALSO:Fibrous materials or films of polymeric organic substances are coloured by graft-polymerizing a dye containing olefinic unsaturated groups with the substance of the fibres or films. Alternatively the materials, e.g. fabrics, are dyed by applying thereto an aqueous dispersion of a polymeric substance on which has been grafted a dye bearing a polymerizable olefinic group. The examples describe the application to cotton fabrics of aqueous dispersions of graft copolymers containing the dimethylol compound of butanediol-1, 4-diurethane as a cross-linking agent, followed by drying at 140 DEG C., the graft copolymers specified being obtained by graftin: (1) isobutyl 1-amino-4-acryloylaminoanthraquinone 2-carboxylate and butyl acrylate on to a copolymer of butyl acrylate and methylol methacrylamide; (2) the coupling product of diazotized 2-amino-4-sulphonic acid-41-acryloylamino-diphenyl sulphone and 3-sulphonic acid-7-aminonaphthol-1 on to a copolymer as in (1); (3) the coupling product of diazotized 1-acryloylamino-4-aminobenzene and 1-phenyl-(21-chloro-41-sulphonic acid)-3-methylpyrazolone-5 on to a copolymer of butyl acrylate, acrylonitrile and methylol methacrylamide; and (5) a dye as in (3) on to a copolymer of butyl acrylate and methacrylamide. The dyeing of textiles such as polypropylene textiles by direct graft-polymerization with polymerizable dyes is referred to. Specifications 877,402, 914,354, 946,472, 948,694 and 952,810 are referred to.

The phenoplast may be a condensate of phenol or cresol with formaldehyde. The aminoplast may be a condensate of formaldehyde with urea, thiourea, melamine, ammeline, guanidine, dicyandiamide, glyoxalureides or ethylene urea. The binders may be dissolved in water, optionally with the addition of water-miscible organic solvents, e.g. alcohols, ethers or ketones; dyes and pigments; and levelling aids such as glycol ethers, acetals, glycols, dimethyl formamide, sulphones and sulphoxides.

The compositions may be used for coating wood, metal and plastics; impregnating fabrics and paper; and laminating; and may be cured by heating, optionally in the presence of acid reacting substances such as carboxylic acids and ammonium nitrate or chloride.

    Abstract: The pile of pile fabrics, e.g. carpets, velvet, plush, cord and velveteen, derived for example from natural or regenerated cellulose fibres, wool, silk, cellulose ester, polyamide, polyester and acrylonitrile polymer fibres, is secured by treating the reverse side of the fabrics with dispersions of copolymers derived from 1-25% by weight of an N-methylolamide of an acrylic acid that may be etherified and 99-75% by weight of one or more other polymerizable compounds and subjecting the fabrics to a heat treatment at a temperature above 100 DEG C. In addition to the N-methylolamide of an acrylic acid or ether thereof the copolymer may also comprise other unsaturated carboxylic acid amides, derivatives of these carboxylic amides which are mono substituted at the nitrogen atom and the methylol compounds of these amides, esters, nitriles and N-disubstituted amides of unsaturated carboxylic acids, vinyl esters, halides, cyanides, ethers, ketones and aromatics, vinylidene halides and cyanides, C-vinyl pyridine, N-vinyl compounds, e.g. N-vinyl imidazole, N-vinyl pyrrolidone, N-vinyl caprolactam and N-vinyl pyridine, unsaturated aldehydes and esters of unsaturated alcohols, e.g. allyl and methallyl alcohols. The fabrics may be treated on the reverse side with aqueous dispersions of the copolymers having a concentration of 3-50% with reference to the weight of the liquor by coating or padding, dried at temperatures up to 100 DEG C. and then heat treated at temperatures above 100 DEG C. The dispersions may also contain thickeners, e.g. starch, cellulose and starch ethers, polyacrylic acids and their salts and salts of copolymers derived from acrylonitrile and acrylic acid, resin forming substances, e.g. tetramethylol acetone, dimethylol acetal, dimethylol urea, trimethylol melamine, dimethylol ethylene urea, dimethylol glyoxal monoureine, dimethylol butane diol diurethane, dimethylol adipamide, dimethylol propylene urea, dimethylol alkyl triazones and ethers thereof and polyfunctional epoxy compounds such as glycol and diglycol diglycidyl ethers, in combination with hardening catalysts, organic and inorganic fillers and pigments, polyacrylamides, polyvinyl ethers, polyvinyl esters, polyvinyl alcohol, clay, kaolin, china clay, barium sulphate, calcium carbonate, titanium dioxide, zinc oxide, iron oxide, chromium oxide and substative dyes. The treatment may be carried out in conjunction with a padding impregnation with a water repellant comprising a metal salt/paraffin emulsion or silicone.
