Abstract

Finely divided organic dyes are isolated from non-aqs. dispersions of the dyes in org. solvents, which have a m.p. of -20 to 120 degrees C and evaporate without decomposition, by solidifying the liquid dispersion, and removing the org. solvent by sublimation. Gives finely divided org. dyes with a particle size esp. suitable for use in paints. The process is rapid and economical, and avoids agglomeration of the dyes.
