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: Highly concentrated, finely dispersed, dispersant-poor or dispersant-free preparation of active substances in solid form hardly soluble to insoluble in water, dispersible in aqueous media, process for making these preparations and applications of same.The preparation contains:(a) 40 to 90% by weight of at least one active substance hardly soluble or insoluble in water with a mean particle size less than 5 microns,(b) 10 to 60% by weight of at least one water-soluble salt of an acid resin, and(c) 0 to 50% by weight of further additions such as dispersants, wetting agents or diluents or a mixture of these.The preparation is finely disperse and in the form of a powder or granulate.The preparation can be made as follows:(a) a mixture of active substance(s) and water-insoluble acid resin is treated with a solution of alkalies or amines in water or solvents and the liquid then is removed.(b) a mixture of active substance(s) and water-insoluble acid resin is exposed to the vapors of ammonia or volatile amines.

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: Process for the preparation of concentrated formulations, which can be dispersed in aqueous media, in the form of free-flowing, low-dusting powders or granules starting from active substances which are sparingly soluble to insoluble in water, such as pigments, dyestuffs, optical brighteners, and other related types of additives.

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.

Abstract: New aqueous, stable, highly concentrated, finely dispersed, flowable dyestuff preparations having a low content of dispersing agents and a high content of dyestuff insoluble to difficultly soluble in water are described, which dyestuffs have a particle size smaller than 10 .mu., particularly smaller than 2 .mu., the said preparations being characterised in that they contain at least 10 percent by weight of water, at least 30 percent by weight of a finely dispersed dyestuff, especially a disperse or vat dyestuff, and a mixture consisting of at most 10 percent by weight of an anionactive dispersing agent, at most 5 percent by weight of a nonionic dispersing agent and at most 35 percent by weight of a hydrotropic agent as well as, optionally, further additives.

Abstract: A process for the manufacture of colored shaped articles from high polymer synthetic resins, wherein water-insoluble, hydrophobic, high polymer synthetic resins in solid form, especially in the form of granules or powders, in a mixture of hydrophilic and organophilic solvents that are reciprocally soluble in one another only to a limited extent and form a two-phase system, are treated with dyestuffs or optical brighteners, the solubility of which in the organophilic portion of the two-phase system is greater than in the hydrophilic portion, the solvent is removed, the synthetic resin dried and shaped, optionally with addition of untreated high polymer fully synthetic resin, from the melt or from a solvent.

Abstract: Liquid to pasty dyestuff preparations are described consisting of at least 35 % of an optionally hydrous solvent from the class of alcohols, esters, ethers or ketones having a boiling point of above 90.degree.C, at least 10 % and at most 40 % of a dyestuff or optical brightener and at least 5 % and at most 25 % of a partially or fully synthetic thermostable synthetic resin present in the dissolved form. These preparations are useful for the coating of compounds of thermoplastic high polymers in the form of granulates or in the form of flakes or powders, particularly those made from polyester, polyamide and polypropylene.
