Abstract
Compounds of the probable formula R.S.S.R, where R is a dyestuff are prepared by contacting a compound of the formula R(SSO3M)n, where n is 1-4 and M is H, NH4 or a metal, in the presence of water with a simple salt of Hg, Ag or Cu or with a compound of the formula A2[HgX4], where A is H, NH4 or an alkali metal and X is halogen, CN or SCN, the salt being soluble in water to the extent of at least 0.01 mols, per litre at 20 DEG C. R may be an azo, disazo, anthraquinone, vat, acridone, phenazine, oxazine, dioxazine, diphenylmethane, triphenylmethane, nitro, phthalocyanine or metallo-phthalocyanine dye.ALSO:Dyes of the formula:- p R-[SOO3M]n wherein R contains the chromophore group and may also contain other solubilising groups, e.g. -SO3M, -COOM, or -OH, n is 1 - 4, and M is H1, NH4 or a metal, normally alkali metal, atom, are applied to textile materials of natural or regenerated cellulose, cellulose acetate or triacetate, aromatic polyesters, acrylic polymers, polyamides, polyolefins, wool and silk and converted to their insoluble form in the presence of simple salts of Hg, Ag or Cu or complex salts of the formula: M2[HgX4] where X is a halogen, e.g. Br or I, -CN or -SCN and M is -NH4, H or an alkali metal, the salt being soluble in water to an extent of at least 0.01 mols per litre at 20 DEG C. The dyes may be from the azo, anthraquinone, vat, acridone, phenazine, oxazine, dioxazine, di- and tri-phenylmethane, nitro, phthalocyanine (which may contain metal) dyestuff series and the -SSO3M groups may be attached direct to aromatic nuclei of the chromophore or via a bridge comprising an aliphatic or aromatic radical which may contain hetero atoms. Stable aqueous dye solutions may be prepared containing both the dye and a simple salt of copper or one of the complex compounds wherein X is Br, I, CN or SCN, e.g. K2[HgBr4] or (NH4)2 [HgI4], otherwise the dye and the metal salt or complex are applied in separate operations. The textile materials may be simultaneously finished and dyed by applying a suitable agent in the solutions containing the metal ions; especially cellulose materials may be cross-linked by including formaldehyde in the solution together with a curing agent, e.g. a metal salt which is a Lewis acid in the solid state. Examples are given.
