    Abstract: A print paste consists of a hydrocarbon liquid phase and an aqueous phase and contains as colouring agent a coloured copolymer prepared from 10 to 70 parts by weight of an ester of (a) acrylic or methacrylic acid, and (b) an aliphatic or cycloaliphatic alcohol having at least six carbon atoms; 1 to 40 parts of a comonomer containing an N-methylol group or N-methylol ether group; 1 to 12 parts of a copolymerizable dye; 4 to 15 parts of an alpha, beta-unsaturated mono- or di-carboxylic acid; 0 to 20 parts of an unsaturated polymerizable hydroxy compound and 0 to 84 parts of one or more other monomers; at least 50% of the free carboxyl groups in the copolymer having been neutralized by ammonia or nitrogenous organic bases. Suitable N-methylol monomers are the alkyl ethers of N-methylol arylamide and N-methylol methacrylamide and of carboxylic imides. Preferred dyes are azo and anthraquinone dyes. The organic base may be an aliphatic or heterocyclic amine. The print paste may include an aminoplast-forming substance and a cure catalyst. In Example 1, a xylene solution of a copolymer formed from alpha - ethylhexyl acrylate, N - butoxymethyl acrylamide, styrene, butanediol monoacrylate, acrylic acid and 2,4,5-trichloro-41-(N-ethyl-N-acryloyloxyethyl)-azobenzene which has been neutralized with dimethyl ethanolamine is mixed with water, NH4NO3 and white spirit. The azo dye may be replaced by 4-nitro-41-(N - ethyl - N - acryloyloxyethyl) - azobenzene or 1 - amino - 2 - isopropylcarboxy - 4 - acryloylaminoanthraquinone. In Example 2, N-butoxymethyl methacrylamide and hydroxy-5 - tertiary butyl - 41 - acryloylaminoazobenzene replace the N-methylol ether and the azo dye used in Example 1. The pastes are used to print fabrics (see Division D1).ALSO:An emulsion-thickened print paste consists of a hydrocarbon liquid phase, an aqueous phase and a coloured copolymer which has been prepared from: 10 to 70 parts by weight of an ester of (a) acrylic or methacrylic acid and (b) an aliphatic or cycloaliphatic alcohol having at least six carbon atoms; 1 to 40 parts of a comonomer containing an N-methylol or N-methylol ether group; 1 to 12 parts of a copolymerisable dye; 4 to 15 parts of an alpha, beta-unsaturated mono- or di-carboxylic acid; 0 to 20 parts of an unsaturated polymerisable hydroxy compound; and 0 to 84 parts of one or more other monomers; at least 50% of the free carboxyl groups in the copolymer having been neutralised by ammonia or nitrogenous organic bases. In Example 1 a xylene solution of a copolymer formed from alpha-ethylhexyl acrylate, N-butoxymethyl acrylamide, styrene butanediol monoacrylate, acrylic acid and 2, 4, 5-trichloro-4\sv - (N - ethyl- N -acryloyloxyethyl)-azobenzene which has been neutralised with dimethyl ethanolamine is mixed with water, NM4NO3 and white spirit. Cotton cloth is printed with the resulting paste and heated to yield orange prints. Red or violet prints are obtained when the azo dye is replaced by 4-nitro-4\sv-(N-ethyl-N-acryloyloxyethyl)-azobenzene or 1-amino-2-isopropylcarboxy - 4 - acryloylaminoanthraquinone. In Example 2, N-butoxymethyl methacrylanide and hydroxy - 5 - tertiarybutyl-4\sv-acryloylaminoazobenzene are used in place of p the N-methylol ether and azo dye in Example 1 and the paste is used to print cotton or polypropylene.

    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.
