Abstract: This invention relates to a process for conditioning organic pigments by(a) grinding a crude organic pigment at a temperature of about 0.degree. C. to about 100.degree. C. in the presence of (i) about 1 to about 10 parts by weight, relative to the organic pigment, of an inorganic salt and (ii) about 1 to about 5 parts by weight, relative to the organic pigment, of a liquid in which the organic pigment and salt are substantially insoluble, to form a pigment paste;(b) grinding the pigment paste at a temperature of about 0.degree. C. to about 100.degree. C. in the presence of about 0.05 to about 1 parts by weight, relative to the organic pigment, of a C.sub.8 -C.sub.10 alkanoic acid to form a treated pigment paste;(c) stirring the treated pigment paste with water or water containing an acid and/or an organic liquid to complete the conditioning of the organic pigment; and(d) isolating the conditioned organic pigment.
