Patent ID: 8808947

Claim:
A polymer compound represented by the following Formula (2): wherein, in Formula (2), R 3 represents an organic linking group having a valency of (m+n); R 4 and R 5 each independently represents a single bond or a divalent organic linking group; A 2 represents a monovalent organic group comprising at least one moiety selected from an organic dye structure, a heterocyclic structure, an acidic group, a group having a basic nitrogen atom, a urea group, a urethane group, an alkoxysilyl group, an epoxy group, an isocyanate group, and a hydroxyl group; A 2 s, n in number, are independent from each other and may be the same or different from each other; R 4 s, n in number, are independent from each other, and may be the same or different from each other; m is from 1 to 8; n is from 2 to 9; m+n is from 3 to 10; P 2 represents a polymer skeleton selected from a vinyl polymer or copolymer; when m is 2 or greater, R 5 -P 2 s, m in number, represent polymer skeletons that are the same as each other; and S represents a sulfur atom.
