Abstract: A process for producing agglomerates of water-soluble dyes by adding a granulating auxiliary to at least one water-soluble dye, which is in pulverulent form, and converting the mixture, while it is being subjected to a tumbling and/or mixing action, by particle enlargement into a granular form, in which process there is used as a granulating auxiliary:(a) at least one compound of the formula IA--(CH.sub.2 CH.sub.2 O).sub.n --H (I)in which A is the group R--O-- or ##STR1## R is an aliphatic or alicyclic hydrocarbon radical containing 8 to 22 carbon atoms, R' is an aliphatic hydrocarbon radical containing 8 to 22 carbon atoms, and n is 10 to 200, or(b) a mixture of a compound of the formula II ##STR2## in which m is 50 to 500, and x is 3 to 5, with a compound of the formula IIIR.sub.1 --NH--CO--NH--R.sub.1 (III)in which each R.sub.

Abstract: The dispersion contains(a) from 30 to 60% by weight of one or more active ingredients having a mean particle size of less than 5.mu.,(b) from 0.1 to 5% by weight of one or more water-soluble homopolymers or copolymers of a N-vinyl-lactam,(c) from 0.1 to 5% by weight of one or more anionic compounds devoid of dispersant character,(d) from 0 to 30% by weight of one or more humectants and(e) water.The active ingredient is sparingly soluble or insoluble in water.The copolymer may be derived from two or more different N-vinyl-lactams or from one or more N-vinyl-lactams and one or more other compounds copolymerizable therewith.The anionic compound or compounds is or are chosen from the group comprising water-soluble alkali metal salts or ammonium salts of aromatic monosulfonic acids, disulfonic acids and trisulfonic acids, which acids may be substituted by alkyl groups of at most 8 carbon atoms or by a cycloalkyl group of at most 6 carbon atoms.

Abstract: Disclosed is a process for washing dyed or printed textile material to remove unwanted substances from the dying or printing process, comprising the steps of applying to the textile material a foam which is produced from a liquid and contains at least one surface active agent and a component which is soluble in the liquid, has substantially no affinity for the fibers of the textile material and possesses a substantial adsorption capacity for the substances to be removed; working the foam into the textile material; and removing the foam. Also disclosed is a liquid composition for carrying out the disclosed process.
Abstract: A process for dyeing hair comprises in sequence applying to the hair an oxidation hair dye composition comprising a mixture of an oxidation dye, a cationic polymer and an oxidizing agent in an oxidation dye carrier, permitting said oxidation hair dye composition to remain in contact therewith for a time ranging from about 15-40 minutes, rinsing the hair with water, then applying to the rinsed hair a shampoo composition containing an anionic detergent and thereafter rinsing said hair with water.

Abstract: The invention seeks to provide a free-flowing formulation of one or more disperse dyes, with which packages can be dyed homogeneously by the HT process without filtering out of the dye, and which is suitable for the thermosol dyeing process. According to the invention such a formulation comprises one or more disperse dyes (a) enclosed in a matrix of one or more polymers (b) which are soluble, or colloidally soluble, both in water and in an organic solvent, in the form of a solid solution in a state of molecular dispersion or of extremely fine subdivision so that in an X-ray spectrum the dye appears amorphous.The formulations may contain additional assistants conventionally present when dyeing hydrophobic fibers. The formulations contain the disperse dye in an extremely fine state of subdivision. Because of the latter, the formulations give level package dyeings, without filtration of the dye, and very level dyeings when used by the thermofixing process.

Abstract: A process for dyeing or printing organic fibrous material made e.g. of polyamide, polyester or polyacrylonitrile, and also of cellulose, said process comprising the use of a dyeing or printing assistant which contains a quaternary ammonium salt. The salt is a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted n-alkylenediamine, a homopolymer of a vinylpyridine, or a quaternized copolymer of a vinylpyridine and styrene. The reaction product, the homopolymer, and the copolymer are quaternized with e.g. benzyl chloride. The ammonium salt can also be a homopolymer of a vinylbenzyl chloride which is quaternized with a tertiary monoamine. The fibrous material dyed or printed with e.g. direct or disperse dyes or with cationic dyes has excellent levelness, good penetration of the dye, and good wetfastness properties. It is also possible to obtain multi-shade effects by printing the material patchwise with a reserve paste and then dyeing it.
