Abstract

Pulverulent disperse dyestuffs which sublime at 100-230 DEG C can be dispersed in organic solvents, such as are required in the preparation of printing inks, by simply stirring them in if their surfaces are coated with compounds of the formula R-Z wherein R denotes a hydrophobic radical with at least 5 C atoms, preferably at least 10 C atoms, and Z denotes the groups -OH, -COOH, -NH2, -O(C2H4O)nH, -NX1X2 or -NH(CH2)mNX1X2, wherein n represents 0, 1 or 2, m represents 2-6 and X1 and X2 represent H or C1-C4alkyl, and they are then ground in impact comminuting equipment (for example pinned disc mills) together with resins which melt above 120 DEG C.
