Title: COMPOSITION, CURED FILM, COLOR FILTER, LAMINATE, AND PIGMENT DISPERSANT
Abstract:
Provided are: a composition, in which the dispersibility and dispersion stability of a pigment can be maintained, and which can be formed into a coating film that can keep the long-term light resistance thereof at a good level under an environment having a low oxygen concentration; and a pigment dispersion. The composition comprises (A) a pigment and (B) a polymer having (b-1) a bulky amine moiety, (b-2) an acid group and (b-3) a constituent unit derived from a macromonomer having a weight average molecular weight of 1000 to 50000 inclusive, wherein the bulky amine moiety (b-1) has a nitrogen atom, carbon atoms (X1) that bind to the nitrogen atom and carbon atoms (Y1) that bind to the carbon atoms (X1), and wherein the total number of the carbon atoms (X1) and the carbon atoms (Y1) is 7 or greater.
