摘要: Case 3-12381/MA 1755/+ A PROCESS FOR THE PRODUCTION OF PIGMENT COMPOSITION ABSTRACT DISCLOSURE .A process for the production of a pigment composition useful in pigmenting surface coating comprising: (a) milling crude copper phthalocyanine blue presence 0-50% (by weight milled material) salt; and (b) subsequently treating material with polar aliphatic solvent; whereby (c) 8 to 12% by weight, based on pigment, additive formula I ( ) wherein CuPc is residue phthalocyanine, m n are each an integer from 1 4, R1 R2 alkyl group having 4 carbon atoms, or R2, to-gether N atom which they bonded, form heterocycle, added prior to, during after solvent treatment step (b);and, (d) then isolated.
