Abstract: Highly concentrated, dust-free, solid and readily dispersible pigment formulations contain(a) from 70 to 95% by weight of one or more finely divided pigments,(b) from 5 to 30% by weight of one or more surfactants which possess 20-45% by weight of ethylene oxide units, have a mean molecular weight of from 4,000 to 15,000 and are obtained by reacting an amine of the formula ##STR1## where R is C.sub.2 -C.sub.6 -alkylene, R.sup.1 is H or C.sub.1 -C.sub.4 -alkyl and n is 1, 2, 3, 4 or 5, or R is 1,3-phenylene, 1,4-phenylene or 4,4'-diphenylenemethane, R.sup.1 is H and n is 1, with propylene oxide and then reacting the product with ethylene oxide, and(c) from 0 to 5% by weight of waxes and/or antifoams, with or without(d) other agents conventionally used in pigment formulations, the percentages being based on (a+b+c).The formulations are very useful for pigmenting aqueous, alcoholic or aqueous/alcoholic printing inks and surface coatings, and printing pastes for textiles.

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: The invention relates to an aqueous disperse dye or optical brightener formulation which comprises(a) from 5 to 55 percent by weight, based on (a+c), of one or more finely divided dyes, optical brighteners or mixtures of these,(b) from 10 to 200 percent by weight, based on (a), of a water-soluble surfactant of the formula ##STR1## where X is from 0 to a mean value of 125, Y is from a mean value of 37 to a mean value of 250, but if X is >37, Y:X is at least 1:1, Z is 0 or 1 and Me.sym. is an alkali metal ion, or mixtures of such surfactants,(c) from 45 to 95 percent by weight, based on (a+c) of water or of a mixture of water and a water-retaining agent, with or without(d) further additives conventionally present in aqueous formulations.

Abstract: Easily water-dispersible pulverulent formulations of disperse dyes are prepared by spray-drying a dye solution which comprises(a) one or more disperse dyes,(b) one or more water-soluble anionic dispersants,(c) from 0 to 20% by weight, based on (a+b+c+d), of other surfactants and(d) from 0 to 20% by weight, based on (a+b+c+d) of agents which serve as protective colloids (the proportion of (c+d) being at most 20% by weight).Suitable solvents (e) are formic acid, formamide, N-methylformamide, butyrolactone, ethylene glycol and propylene glycol, which may in addition contain up to 100% by weight, based on (e), of N,N-dimethylformamide or acetic acid or mixtures of these. The formulations obtained by the above process contain the dye in very fine dispersion.

Abstract: Oxyalkylated bisphenols are obtained from 2,2-(p,p'-bishydroxydiphenyl)-propane and styrene in the presence of an acid catalyst and are then oxyalkylated, after which they may or may not be sulfated.

Abstract: New and valuable herbicide based on 1-phenyl-4-amino-5-chloro (or -5-bromo)-pyridazone-(6) in the form of an aqueous suspension.

Abstract: Aqueous pigment formulations containing glycol and having good flow, good water retention and good flocculation resistance which contain dipropylene glycol as a flow improver. The formulations are particularly suitable for pigmenting aqueous polymer dispersions and textile pigment printing and dope dyeing.

Abstract: Powdered, highly concentrated and stably dispersible dye formulations which are substantially devoid of dye agglomerates, which contain dyes which are not soluble in water such as disperse dyes or vat dyes, anionactive dispersing agents and (as stabilizing agent) from 2 to 30% by weight based on the dye of a polyethylene oxide having a molecular weight of from 200 to 1000 or a reaction product which has been obtained froma. C.sub.6 to C.sub.20 fatty alcohols;B. alkylphenols of C.sub.4 to C.sub.12 in the alkyl;C. C.sub.14 to C.sub.20 fatty amines;D. castor oil or hydrogenated castor oil;E. C.sub.14 to C.sub.20 fatty acids; orF. natural resin acidswith from 2 to 80 moles of ethylene oxide per mole of OH or NH.sub.2 groups; or fromalkylenediamines of two to five carbon atoms with from 25 to 120 moles of propylene oxide and ethylene oxide per mole of NH.sub.2 groups. The formulations are stable in storage at 60.degree.C and remain devoid of dye agglomerates.

Abstract: A new .beta.-modification of the dye of the formula: ##SPC1##Which is eminently suitable for dyeing polyesters in particular and which is surprisingly more stable under dyeing conditions than the modification already known.

Abstract: An aqueous pigment dispersion which contains (a) pigment, (b) a water-soluble surfactant and water and a water-retaining agent in which (b) is a reaction product of a polyhydroxyl compound with from 3 to 50 moles of propylene oxide and from 2 to 70 moles of ethylene oxide per equivalent of hydroxyl. The dispersions give bright and deep-shade emulsion paints or distempers containing cellulose ethers.
