Abstract: PROBLEM TO BE SOLVED: To obtain the subject granular pigment composition that can suppress marked dust pollution on the handling, improve the fluidity when it is fed to a container and is useful for coloring polymer materials by formulating the inorganic pigments and the organic pigments in specific amounts. SOLUTION: This pigment composition comprises (A) 50-99.5 wt.% of at least one of inorganic pigments (suitably bismuth vanadate pigment and/or rutile pigment or the like) and (B) 0.5-50 wt.% of at least one of organic pigments (suitably quinophthalone pigment and/or isoindoline pigment). In addition, a mixture of a plurality of yellow pigments or a yellow pigment and an orange pigment, red pigment, brown pigment and/or blue pigments may be included in this composition. The objective pigment is preferably prepared by together wet-grinding the crude pigments occurring in the synthesis of pigments and the resultant pigment suspension on the grinding are dried, as their mixing is continued.

Abstract: Pigment composition in granule form contains 50-99.5 wt.% inorganic pigment, and 0.5-50 wt.% organic pigment. An Independent claim is also included for a process for producing the pigment composition comprising wet grinding the crude pigments and drying the pigment suspension obtained.
