Abstract

Dye preparations comprising one or more dyes with no water-solubilizing groups in the molecule from the class of the metal complex azo dyes or the metal phthalocyanines and reaction products between from 1 to 50 mol of ethylene oxide and 1 mol of castor oil are useful for coloring granular or pulverulent substrates and for preparing aqueous dye preparations useful in printing inks.
