ABSTRACT:
Process for the production of fine-particle, essentially amorphous dye or drug preparations by converting a relatively coarse-particle dispersion or a solution into a colloidal dispersion in water, where the colloidal dispersion is generated at a temperature above the melting point of the dye or drug by admixing appropriately hot water (where appropriate under pressure) or an aqueous protective colloid solution so that an emulsion of a melt in aqueous medium is produced and is immediately spray-dried or converted by cooling into a suspension.
