Title:
PIGMENT DISPERSANT, PIGMENT COMPOSITION, AND COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/051875
Kind Code:
A1
Abstract:
The problem to be solved by the present invention is to provide: a pigment dispersant with which even pigments having poor dispersion stability can be easily dispersed and which further has the effect of improving the coloring power; a pigment dispersion composition obtained using the pigment dispersant; and a coating material comprising the pigment composition.
The problem is solved by providing a pigment dispersant represented by formula (I).
(In formula (I), R1 and R2 are each independently a di(C1-6 alkyl)amino(C2-6 alkyl) or tri(C1-6 alkyl)amino(C2-6 alkyl) group and R3 to R10 are each independently a hydrogen atom, halogen atom, hydroxyl group, (un)substituted amino group, nitro group, cyano group, (un)substituted alkyl group, etc.)
