Abstract: A process for producing a liquid formulation of salts of sulfonated azo dyes by coupling an at least equimolar amount of diazotized aminoarylsulfonic acids I H2N—Ar—SO3H (I), where Ar is phenylene (which may be monosubstituted by sulfo) or naphthylene (which may be mono- or disubstituted by sulfo and/or monosubstituted by hydroxyl) onto the coupling product of an unsubstituted or methyl-substituted phenylenediamine with itself comprises dissolving the azo dye in a basic medium and then subjecting the solution to a nanofiltration.

Abstract: A colloid disperse dye preparation is prepared by preparation of an emulsion, which contains drops of a dye melt emulsified in a non-solvent, at elevated temperature, subjecting the emulsion to shear forces to reduce the average drop size to below 5 mu m, and cooling the emulsion below the melt temperature of the dye. Preparation of colloid disperse dye preparations comprises: (a) preparation of a crude emulsion, which contains drops of a dye melt emulsified in a non-solvent, at elevated temperature; (b) subjecting the crude emulsion to shear forces, so that the average size of the drops is reduced to below 5 mu m; and (c) cooling the resulting emulsion below the melt temperature of the dye. Independent claims are included for: (A) dye preparation obtainable by the above process; (B) dye preparation comprising dye particles which: (i) have an average particle size below 5 mu m; (ii) are spherical; and (iii) are spherical; and (C) inkjet ink which comprises a dye preparation as described in (A) or (B), optionally in combination with other auxiliaries.
