Patent ID: 8278386

Claim:
A dispersion composition comprising: (A) titanium black; (B) a graft copolymer; and (C) a solvent, wherein the graft copolymer comprises at least a structural unit represented by any one of the following Formula (1) to Formula (5): wherein, in Formula (1) to Formula (5), X 1 , X 2 , X 3 , X 4 , X 5 , and X 6 each independently represents a hydrogen atom or a monovalent organic group; Y 1 , Y 2 , Y 3 , Y 4 , and Y 5 each independently represents a divalent linking group; Z 1 , Z 2 , Z 3 , Z 4 , and Z 5 each independently represents a hydrogen atom or a monovalent organic group; R represents a hydrogen atom or a monovalent organic group; R's having different structures from one another may be present in the copolymer; and n, m, p, q, and r each independently represents an integer of from 1 to 500; and the divalent linking group represented by Y 1 , Y 2 , Y 3 , Y 4 or Y 5 is any one selected from the following linking groups (Y-1) to (Y-20): wherein, in (Y-1) to (Y-20), A represents a bond to a left terminal end group in any of Formula (1) to Formula (5), and B represents a bond to a right terminal end group in any of Formula (1) to Formula (5).
