    Abstract: 1,153,565. Preventing dye migration. BADISCHE ANILIN - & SODA - FABRIK A.G. 7 Oct., 1966 [9 Oct., 1965], No. 44875/66. Heading D1B. Dye migration in pad dyeing of fibrous material with vat, disperse and/or fixing dyes is prevented by applying before, during or immediately after the padding in of the dye a cationic polymer which is a polymer or copolymer of a vinylimidazole or ethyleneimine polymer or a salt or quaternary ammonium compound of such a polymer or copolymer. In particular poly - N - vinylimidazole is particularly advantageous as are the quaternary ammonium compounds of polyethyleneimine in which up to 20% of the nitrogen atoms have been quatenized. Preferably the cationic polymer is applied together with the dye by dissolving in the padding liquid. In examples cotton, rayon, polyester, cellulose triacetate, nylon, and mixtures of polyester/cotton and polyester/rayon materials are dyed. 2.5 to 200% by weight of polymer with reference to the dye is preferably used. Specified compositions for use in the above process are referred to.

    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.

    IPC: C09B45/14

    Abstract: The dyes of formulae are prepared by conventional diazotization and coupling processes.ALSO:The invention provides a process in which metal containing polypropylene is dyed with monoazo dyes of general formula:- in which R1 is an unsubstituted or substituted alkyl or aryl radical, R2 is an unsubstituted or substituted aryl radical and the ring A may have non-ionic substituent e.g. halogen atoms, or alkyl or alkoxy dialkylamino or acrylamino groups. Metals present in the polypropylene may be zinc, aluminium, chromium, cobalt, iron or nickel, dyeing is advantageously effected at 70-130 DEG C at pH 4-5 conventional thickeners and dispersing agents being used.

    Abstract: The invention comprises dyes of the formula:- in which Y is a substituted or unsubstituted aromatic acyl radical of a monocarboxylic acid free from sulphonic acid halogen alkylamide groups and chloro- or bromo-methyl groups and Z is a cation. The dyes are made by reacting a compound of the formula:- with an acid halide A-Y where A is chlorine, bromine or fluorine. Radicals mentioned for Y are benzoyl, benzoyl substituted by chloro-, nitro-, methyl-, methoxy-, trifluoromethyl-, N-methyl sulphonamide, N-ethyl sulphonamide, N:N-dimethyl sulphonamide or pyrrolidinosulphonyl groups and naphthoyl. Examples are given. The dyes dye and print linear polyamides and polyurethanes in blue shades.
