Powdered, highly concentrated and stably dispersible dye formulations

Claim 1

A powdered, highly concentrated and stably dispersible dye formulation which is practically devoid of dye agglomerate and which consists essentially of: A. at least one water-insoluble dye; B. at least one anion-active dispersing agent in an amount sufficient to disperse said dye in water; and C. as a stabilizing agent from 2 to 30% by weight, with reference to said dye, of an oxyalkylation product which is (C.1) a reaction product of a. a saturated fatty alcohol or unsaturated fatty alcohol, each of 6 to 20 carbon atoms, or a mixture thereof; b. an alkylphenol of 4 to 12 carbon atoms in the alkyl; c. a saturated fatty amine or unsaturated fatty amine, each of 14 to 20 carbon atoms, or a mixture thereof; d. castor oil or hydrogenated castor oil; e. a saturated fatty acid or unsaturated fatty acid, each of 14 to 20 carbon atoms, or a mixture thereof; or f. a natural resin acid, with from 2 to 80 moles of ethylene oxide per mole of hydroxyl or amino groups reactive with ethylene oxide; (C.2) a reaction product of g. an alkylenediamine of 2 to 5 carbon atoms with from 25 to 120 moles of propylene oxide and ethylene oxide per mole of amino groups, at least 20 moles of ethylene oxide being used per mole of amino groups; (C.3) a polyethylene oxide of a molecular weight of from 200 to 1,000; or (C.4) a mixture of two or more of the oxyalkylation products designated
