ABSTRACT:
The invention pertains to a highly concentrated pigment comprisingfrom 75 to 95% by weight, preferably from 78 to 95% by weight, most preferred from 80 to 95% by weight, based on the weight of the composition, of a pigment;from 0 to 20% by weight, preferably from 5 to 18% by weight, based on the weight of the composition, of a resin;the total of pigment and resin being from 85 to 98% by weight of the composition; andfrom 1 to 15% by weight, preferably from 2 to 15% by weight, most preferably from 5 to 15% by weight, based on the weight of the composition, of a C10-C18alcohol, a liquid hydrocarbon having a boiling point higher than 80° C. at 105Pa, or both a C10-C18alcohol and a liquid hydrocarbon having a boiling point higher than 80° C. at 105Pa.Also claimed are a process for its manufacture, comprising dry-milling, blending and kneading the components, and the use of the pigment concentrates for the preparation of a masterbatch, ink, coating, plastic material, toner or colour filter.
