Water-soluble latent curing catalysts for textile treatment resins

A composition suitable for treating textile materials comprises an aqueous solution containing (1) a nitrogenous resin-forming composition, such as the methylol derivatives or the methyl, ethyl, propyl and butyl-ethers of methylol derivatives of monomeric or polymeric compounds containing a plurality of amino or mono-substituted amino groups, the compounds being known to form resins by condensation with formaldehyde, and (2) a water-soluble halogens-1 : 3 : 5-triazine as latent curing catalyst. Suitable amino compounds are monomeric nitrogen compounds, e.g. urea, thiourea, substituted ureas and thioureas, dicyandiamide, dicyandiamidine, biguanides, amides, carbamates, allophanates, heterocyclic compounds, e.g. aminotriazines, ureins, ureides, imidazolidones, triazones and hydantoins or mixtures of such compounds, and polymeric nitrogen compounds, e.g. polymeric amides made by the reaction of dibasic acids with diammes. The halogeno-1:3:5-triazines used as latent curing catalysts may be mono- and di-halageno-1:3:5-triazines which contain, attached to at least one of the carbon atoms of the triazine ring through a nitrogen, oxygen or sulphur atom, an organic radical carrying either a negatively charged solubilising group, e.g. a sulphonic or carboxylic group, or a positively charged solubilising group, e.g. a quaternary ammonium group. Triazine compounds containing sulphonic and/or carboxylic acid groups may be used in the form of their salts, e.g. with alkali metals. Several suitable compounds are specified. Preferably, however, the triazine compounds used are water-soluble nitro-dyestuffs containing a mono-or di-halogeno-1:3:5-triazinyl radical or water-soluble dyestuffs of the azo, anthroquinane or phthalocyanine series containing a mono- or di-halogeno-1:3:5-triazinyl radical, so that the textile materials treated are simultaneously coloured. The solution may also contain alkali-metal thio-cyanates, polyhydroxy compounds, e.g. polyvinyl alcohol, cellulose ethers, starches or starch ethers, proteinaceous materials, e.g. casein and gelatin, and/or surface-active agents. The resin may be cured on the treated textile materials by heating to between 100 DEG C. and 150 DEG C. for 1 to 15 minutes.
