Abstract

Procedure for obtaining finely dispersed dye formulations, characterized in that the dye with difficult solubility in water dissolves at temperatures between 80 and 200ºC in those non-ionogenic surfactants that are liquid at these temperatures, but are nevertheless solid at temperature. environment, and corresponding to the general formula. **(See formula)** where R2 and R3 signify hydrogen or one of the moieties R2 and R3 signifies hydrogen and the other signifies methyl, n represents a number from 20 to 200, m represents a number of 1 or 2 and R1 signifies a mono or divalent alkoxy or alkylamino moiety, saturated or unsaturated, with 8 to 22 carbon atoms, a monovalent alkylcarbonylamino residue, saturated or unsaturated, with 8 to 22 carbon atoms, an alkyl sulfonylamino residue with 10 to 18 carbon atoms, an alkylcarbonyloxy residue, saturated or unsaturated, with 8 to 22 carbon atoms, an alkylphenoxy moiety with 8 to 18 carbon atoms in the alkyl part or a phenyl-ethyl, di- (phenylethyl) - or tri- (phenylethyl) -phenoxy moiety, which in the phenyl nucleus may be further substituted by methyl or chlorine, and the melt obtained in this way is then cooled very rapidly.
