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 from A. C6 to C20 fatty alcohols; B. ALKYLPHENOLS OF C4 to C12 in the alkyl; C. C14 to C20 fatty amines; D. CASTOR OIL OR HYDROGENATED CASTOR OIL; E. C14 to C20 fatty acids; or F. NATURAL RESIN ACIDS WITH FROM 2 TO 80 MOLES OF ETHYLENE OXIDE PER MOLE OF OH or NH2 groups; or from ALKYLENEDIAMINES OF TWO TO FIVE CARBON ATOMS WITH FROM 25 TO 120 MOLES OF PROPYLENE OXIDE AND ETHYLENE OXIDE PER MOLE OF NH2 groups. The formulations are stable in storage at 60 DEG C and remain devoid of dye agglomerates.

Abstract: Newcolour-stable beta-modification (I) of the dispersion dye of formula has an x-ray diffraction diagram with lines of the following intensities at a diffraction angle of 2 H: strong at 20.2, 22.4, 22.8 and 23.8 degrees; medium at 8.3, 11.2, 25.3, 26.2, 27.5 and 33.5 degrees; weak at 9.1, 13.2, 14.7, 15.4, 16.7, 17.1, 19.3, 20.7, 26.7, 29.0, 29.9, 30.8 and 32.6 degrees. (I) is used for dyeing textiles of synthetic linear polyesters, in loose or wound form. (I) is dispersion stable and, unlike the alpha-modification (Disperse Orange 61), does not tend to flocculate when kept in aq. medium at high termp. for long periods. Depson. of the dye on the fibre does not occur in any phase in the dyeing of wound matl., e.g. spools.
