Abstract

PURPOSE: To readily obtain title liquid preparation having good storage-stability, by adding a specific surfactant to an aq. dispersion of a water-insoluble azo dye to form a coacervate layer containing the dye, and separating the layer.
CONSTITUTION: The liquid preparation is produced by preparing a water-insoluble azo dye from diazo component, such as aniline, p-toluidine, m-anisidine, or p- chloroaniline, and coupling coumponent, such as p-cresol, resorcinol, or acetanilide, adding to an aq. suspensim of the water-insoluble azo dye a nonionic surfactant or a combination of nonionic and anionic surfactants which are capable of forming an aqueous two-phase system in the presence of a precipitant such as NaCl, forming a coacervate layer containing the azo dye, and separating the layer, for example, by decantation.
