Abstract: A textile printing paste comprises (1) an aqueous solution of an organic binder or salt thereof, of M.W. above 200 having a plurality of basic NH2- and -NH- groups except esters of acrylic acid or of substituted acrylic acid polymers containing amino or imino-groups; (2) a cross-linking agent having a plurality of radicals capable of reacting with the NH2- and NH< groups of the binder; (3) a pigment; and optionally (4) a thickening agent, e.g. tragacanth.  Textiles are printed and dyed by treating them with the paste which is rendered water-insoluble by heating, e.g. with steam, or by alkaline after-treatment.  The organic binder may be the reaction product of an interpolymer of styrene and acrylylfluoride with a diamine, e.g. methyl-propylene diamine, polyvinylsuccinimide or poly N-vinyl phthalimide heated with hydrazine hydrate, the reaction product of chlorinated polyisobutylene with ammonia, polyethyleneimines, polyvinylmethylketones reacted with ammonia, polyacrylonitrile reacted with polyamines, e.g. ethylene diamine, the reaction product of di- or polycarboxylic acids containing imino groups or esters, e.g. iminodipropionic acid with di- or polyamines, e.g. ethylenediamine, the reaction product of di- or polyamines containing imino groups with di- or polycarboxylic acids or their esters, e.g. oxalic acid ester reacted with diethylene triamine, polyurethanes, e.g. the reaction product after the splitting off of the acetyl group of N-acetyldiethanolamine and hexamethylene diisocyanate, the reaction product of o ,o 1-diaminodipropyldiaminobutane with triacryl formal, epichlorohydrin reacted with ammonia, the hydrogenation products of the reaction of pentaerythrite and four mols. of acrylonitrile, the reaction product of acrolein and ammonia or amines, the reaction product of the acetal of chloroacetaldehyde and ammonia, the reaction product of glycerol-tri-sulphuric acid ester, polysaccharides containing -NH2 or >NH groups, amine cellulose, addition products of ethylene imine and cellulose, and hydrolysates of protein substances, e.g. glue, casein, or gelatine.  The cross-linking agent may be a polyisocyanate, e.g. the addition product of one mol. of a diisocyanate with two mols. of a 1,3-diketone or a 1,3-ketone ester, or the addition product of a bisulphite and a diisocyanate, an acid, e.g. adipic, an aldehyde, e.g. glyoxal, chloromaleicdialdehyde, paraldehyde, triacrylformal, acrolein and its derivatives, cyanuric chloride, the reaction product of one mol. of cyanuric chloride with three mols. of ethylene imine, the reaction product of triacrylformal and two or three mols. of ethyleneimine, the reaction product of phosphoric acid-alkyl-ester dichlorides and ethyleneimine, the reaction products of disulphochloride and ethyleneimine, acid polyesters from three mols. of maleic acid anhydride and one mol. of glycerol, hexamethylolmelamine, the reaction product of novolacs with epichlorohydrin, soluble reaction products of dicyandiamide with formaldehyde, quaternary compounds from glycerol-chloroacetic acid ester and three mols. of the addition product of epichlorhydrin and dimethylamine, or the reaction product of long-chain dialcohols, formaldehyde and pyridinium chloride, polymethylol-polyacrylic acid amide or allyl starch. Pigments mentioned are "Indanthrenbrown B.R.," "Heliogenblue B" and "Hansayellow G."  The textile material may be a cotton fabric.  Specification 676,806 is referred to.ALSO:A composition suitable for use as a printing paste comprises an aqueous solution of an organic binder of M.W. above 200 having a plurality of basic NH2- and -NH- groups, e.g. a polymer, a cross-linking agent having a plurality of radicals capable of reacting with said NH2- and -NH- groups, a pigment and optionally a thickening agent, e.g. tragacanth.  The organic binder may be the reaction product of an interpolymer of styrene and acrylyfluoride with a diamine, e.g. methylpropylene diamine, poly-N-vinyl phthalimide or polyvinylsuccinimide heated with hydrazine hydrate, the reaction product of chlorinated polyisobutylene with ammonia, polyethyleneimines, polyvinylmethylketones reacted with ammonia, polyacrylonitrile reacted with polyamines, e.g. ethylene diamine, the reaction product of di- or poly-carboxylic acids containing imino groups or esters, e.g. iminodipropionic acid with di- or polyamines, e.g. ethylenediamine, the reaction product of di- or polyamines containing iminogroups with di- or polycarboxylic acids or their esters, polyurethanes, the reaction product of w,w1-diaminodipropyl-diamino-butane with triacrylformal, epichlorohydrin reacted with ammonia or the reaction product of acrolein and ammonia or amines.  The cross-linking agent may be a polyisocyanate e.g. the addition product of one mol. of a diisocyanate with two mols. of a 1,3-diketone or a 1,3-ketone ester, or the addition product of a bisulphite and a diisocyanate, an acid, e.g. adipic, an aldehyde, e.g. glyoxal, chloromaleicdialdehyde, paraldehyde, triacrylformal, acrolein and its derivatives, cyanuric chloride, the reaction product of triacylformal and two or three mols. of ethyleneimine, the reaction product of phosphoric acid-alkyl-ester dichlorides and ethyleneimine, the reaction products of disulphochloride and ethyleneimine, acid polyesters from three mols. of maleic acid anhydride and one mol. of glycerol, hexamethylolmelamine, the reaction product of novalacs with epichlorohydrin, soluble reaction products of dicyandiamide with formaldehyde, quaternary compounds from glycerol-chloroacetic acid ester and three mols. of the addition product of epichlorohydrin and dimethylamine, or the reaction product of long chain dialcohols, formaldehyde and pyridinium chloride, polymethylol-polyacrylic acid amide or allyl starch.  Pigments mentioned are "Indanthrenbrown B.R," "Heliogenblue B" and "Hansayellow G."  In examples, (1) an interpolymer of styrene and acrylylfluoride is after-treated with methylpropylenediamine; (2) a polyester from adipic acid and ethyleneglycol of a hydroxyl number of 62 and an acid number of 0.6 is after-treated successively with hexanediisocyanate and methylpropylenediamine; and (3) N-vinylsuccinimide is polymerized in bulk, then after-treated with hydrazinehydrate.  The compositions are used as textile printing pastes (see Group IV (c)) and for coating paper and textiles to render them water-repellent.  Specification 676,806 is referred to.
