Abstract:
A composition includes: a compound represented by the following Formula (1); a pigment; and a solvent. In a case where a film having a thickness of 4.0 m is formed using the composition, a maximum value of a light transmittance of the film in a thickness direction in a wavelength range of 360 nm to 700 nm is lower than 40%. In Formula (1), Z1 represents an (m+n)-valent linking group, Y1 and Y2 each independently represent a single bond or a linking group, A represents a group including a pigment adsorption portion, P1 represents a polymer chain, n represents 1 to 20, m represents 1 to 20, and m+n represents 3 to 21, at least one of Z1, A1, or P1 includes a photocurable group.
