Abstract: Dispersion dye prepns. contain (a) 5-40 wt. % one or more finely-divided dispersion dyes or optical brighteners, (b) 5-40 wt. % water-soluble surfactant from reaction of (i) ethylene oxide adducts of polyether diols made by polymerisation of butylene oxide T.H.F. or hexamethylene oxide in presence of acid or alkali, or (ii) adducts of ethylene oxide and propylene oxide on 2-10C diols, polyols and/or bis-(hydroxy cyclohexyl)methane or derivs., with 0.2-1 mol. chlorosulphonic acid, SO3 or sulpho-propionic anhydride per mol OH and subsequent neutralisation, (c) 5-30% usual anionic dispersant, and (d) 40-85% water opt. mixed with a water retention agent, or 10-90% (c) with no (d), and (e) opt. other usual additives. Used for dyeing or brightening of textiles contg. synthetic fibres, esp. wound yarns, e.g. cheeses, of cellulose ester or linear polyester fibres. The dispersions are stable and unchanged after prolonged storage at room temp. or many days at 60 degrees C. They are easily dispersed in water by stirring, and after long heating of dye baths at 110-140 degrees C, no dye flocculation or filtering of dye in outer yarn layers occurs.

Abstract: The dispersions contain (A) 40-60 wt.% dispersion or vat dye, and (B) a dispersing agent obtd. by further condensing (I) a condnsn. prod. of phenol sulphonic acids, free of condensed ring systems, with urea and HCHO in molar ratio 1:1-1.5:1.7-2.2, with (II) a condnsn. product of phenol and formaldehyde made in strongly alkaline medium and then reacted for 1-2 hr. at pH 2-4. Ratio of (A) to (B) is 3-25:1 by wt. (I) and (II) are condensed together in a strongly acid medium. The dispersions are made by milling the dye in aq. suspension in presence of (B) at 20-90 degrees C and have a high dye concn. but are readily pumped and poured and can be easily dispersed in water by stirring. The small amt. of (B) used results in light and brilliant shades without yellowing of the fibres.

Abstract: Pigments are coated with cpds. of formula (I) (in which R is an opt. branched-chain, opt. unsatd. alkyl gp. with (9-25)C atoms.) The amt. of coating material is 0.1-30 (3-15) wt.% of that of the pigment, and R is pref. (15-19)C alkyl, esp. heptadecenyl. The coated pigments have improved dispersibility and are suitable for a wide range of uses, including colouring of paints, printing inks, plastics and leather.

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: Novel beta-modification of the azo dyestuff are of formula (I): (I) shows principal lines on an X-ray diffraction diagram of angel 20: 6.5, 11.4 and 14.2 with intensities of 62%, 76% and 100% respectively, using Cu Alpha radiation. (I) is used for dyeing synthetic polyamide textiles and is colour stable.
