摘要： The invention relates to a process for preparing organic pigment granules with a particular particle size wherein an organic pigment with a particle size of 0.01 to 10 &mgr;m is mixed with water, a C1-C4alcohol, a C3-C8ketone or a mixture thereof, a binder and ammonia or a C1-C3amine and an emulsifier. This mixture is pressed in a continuously operating apparatus through one or more apertures each having a size of 0.2-5.0 mm2, the apparatus consisting of at least one conveying device and a shaping section comprising the apertures, and being constructed, and operated with a throughput, such that the pressure in its shaping section does not exceed 10 bar. The granulated product is then dried at a temperature of −50 to 200° C. at atmospheric pressure or under reduced pressure. The invention also relates to pigment granules prepared by the process of the invention, with a particle size of 0.5 to 4 mm, wherein the pigment present essentially has a particle size from 0.01 to 10&mgr;m.
