Title:
METHOD FOR PRODUCING FINE ORGANIC PIGMENT
Document Type and Number:
Japanese Patent JP2007277449
Kind Code:
A
Abstract:
To provide a method for producing a pigment, solving such problems as much energy consumption as a problem in conventional kneaders, pigment grade such as gloss and coloring power, micronizing level limit and interlot contamination.
The method for producing the fine organic pigment comprises kneading a mixture of an organic pigment, a water-soluble inorganic salt and a water-miscible organic solvent with a planetary-type mixer 1 with multiple blades 4 subject to planetary motion. Owing to the use of such a planetary mixer, the objective finer organic pigment can be obtained with a small amount of energy.
