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: The dispersions contain(a) 30 to 60% by weight of a diazotizable aromatic amine bearing electrophilic substituents and having an average particle size below 10 .mu.m (microns),(b) 0.1 to 5% by weight of a water-soluble polymer or copolymer of an N-vinyl-lactam,(c) 0.1 to 5% by weight of an anionic dispersing agent,(d) 0 to 30% by weight of at least one hydrotropic compound and/or at least one compound which lowers the freezing point and(e) water.The dispersions can be prepared by wet-grinding of the components. They can be used to produce azopigments in substance or azodyestuffs on textile substrates. Their diazotization proceeds very quickly and completely.

Abstract: The unions consist of a mixture of fibers which can be colored with disperse dyestuffs and fibers which can be colored with reactive dyestuffs. A printing paste containing:(a) at least one finely dispersed, water-insoluble azo dye-stuff of the formula: ##STR1## (b) at least one reactive dyestuff and (c) at least one non-ionic surfactant is used. The azo dyestuff of formula I is not prepared in the printing paste. It has a melting point between 220.degree. and 300.degree. C. In the formula, A, D and R have the meanings given in claim 1.In this way, prints are obtained, from which the non-fixed dyestuffs can easily be washed out and which have an excellent white ground. The build-up and fastness properties are good. The prints are very brilliant and deep in color, in particular in the field of orange and red shades.

Abstract: Process for the manufacture of concentrated formulations which are in the form of free-flowing, low-dust powders or granules and are easily dispersible in aqueous and/or organic media, starting from active ingredients which are sparingly soluble or insoluble in water.
