where R
1
represents an (m+n)-valent organic linking group, R
2
represents a single bond or divalent organic linking group; A
1
represents a monovalent organic group having a pigment adsorption structure that contains at least one selected from organic pigment structure, heterocyclic structure, acidic group, group having a basic nitrogen atom, urea group, urethane group, group having a coordinating oxygen atom, hydrocarbon group having 4 or more carbon atoms, alkoxysilyl group, epoxy group, isocyanate group, and hydroxyl group; the n groups A
1
and bonds or groups R
2
may independently be the same or different; “m” is 1 to 8, “n” is 2 to 9, and m+n is 3 to 10; P
1
represents a polymer skeleton; and the m skeletons P
