Abstract: Fibrous material is printed or coloured by applying to the material a composition comprising a solution or dispersion of a water-soluble or water-swellable quaternary polyammonium salt of a polymer derived from an ethylenically unsaturated compound (see Group IV (a)) and a pigment and subsequently heating the treated fibrous material to split the quaternary ammonium salt and to render the composition water insoluble.  The splitting may be effected by steaming.  The composition may also contain an alkaline-reacting buffer substance, thickeners, resins and fillers.  Pigments mentioned are copper phthalocyanine, chlorinated copper phthalocyanine and red iron oxide. The fibrous material may be fabric made of cotton or natural or synthetic fibres, paper or leather.  Exemplified polymers are the pyridinium salt of an interpolymer of methyl methacrylate and vinyl-beta-chlorethyl ether, and the pyridinium salt of a copolymer of butyl acrylate, methyl acrylate, acrylamide and vinyl chloracetate.  The thickening agent may be an aqueous emulsion of benzine, benzene, toluene, xylene, glycerine, trichlorethylene or tragacanth, or a mixture of tragacanth and starch.ALSO:A composition for printing or colouring fibrous material comprises a solution or dispersion, e.g. in water, lower alcohols, acetone, or mixtures, of a water-soluble or water-swellable quaternary polyammonium salt of a polymer derived from an ethylenically unsaturated compound and a pigment. The quaternary salt of the polymer after application to the fabric may be split by heat, e.g. steam, to render it insoluble.  The composition may also contain an alkaline-reacting buffer substance, e.g. sodium acetate, phosphate or borate, thickeners, resins, and fillers.  The quaternary polyammonium salt may be those of poly-alphavinylpyridine or the polyvinyl ether of diethylaminoethanol, or the polymeric ester of dieethylethanolamine of acrylic acid with alkyl or aralkyl halides or a salt derived from a tertiary amine, e.g. pyridine or morpholine and halogen-containing polymers having reactive halogen atoms, e.g. polyvinyl-beta-chlorethyl ether, or of polymers of beta-chloralkyl esters of unsaturated acids, e.g. polyacrylic acid-beta-chlorethyl ester, or of polymers of unsaturated esters from unsaturated alcohols, e.g. polyvinyl chloracetate, polyallyl or polymethallyl chloride, and copolymers of these monomers with each other and other polymerizable compounds such as vinyl chloride, vinylidene chloride, maleic acid esters isoprene, butadiene, acrylic acid, methacrylic acid or the nitriles, amides, or esters of these acids.  Exemplified polymers are the pyridinium salt of an interpolymer of methyl methacrylate and vinyl-beta-chlorethyl ether and the pyridinium salt of a copolymer of butyl acrylate, methyl acrylate, acrylamide and viny chloracetate.  Pigments mentioned are copper phthalocyanine, chlorinated copper phthalocyanine and red iron oxide.  The thickening agent may be an aqueous emulsion of benzine, benzene, toluene, xylene, glycerine, trichlorethylene, or tragacanth, or a mixture of tragacanth and starch.  Resins mentioned are the reaction product of allyl alcohol and ethylene oxide, the reaction product of the disulphochloride of a long chain aliphatic hydrocarbon of 10 to 20 carbon atoms and ethyleneimine, and a precondensate of tetramethylol acetylenediurea.  The composition may be used for printing fabrics, e.g. of cotton, or natural or synthetic fibres, paper or leather.
