Polymer compound

A polymer compound comprising:

• a repeating unit represented by formula (I);
• a repeating unit represented by formula (II);
• and
• a repeating unit represented by formula (III),
• in formula (I), R1 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms;
• X1 represents a single bond or a divalent linking group selected from the group consisting of —O—, —S—, —COO—, —OCO—, —CONR2—, —NR2COO—, —CR2N—, a substituted or unsubstituted divalent aliphatic group, a substituted or unsubstituted divalent aromatic group, and a combination thereof;
• R2 represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or —X1—P1;
• and P1 represents a polymerizable group,
• in formula (II), R10 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms;
• R11 and R12 each independently represent a hydrogen atom, a substituted or unsubstituted aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
• R11 and R12 may be linked to each other through an alkylene linking group, an arylene linking group, or a linking group of a combination thereof;
• X10 represents a single bond or a divalent linking group selected from the group consisting of —O—, —S—, —COO—, —OCO—, —CONR13—, —NR13COO—, —CR13N—, a substituted or unsubstituted divalent aliphatic group, a substituted or unsubstituted divalent aromatic group, and a combination thereof;

• in formula (III), R20 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms;
• R21 represents an alkyl group having 4 to 20 carbon atoms, an alkyl group having 1 to 20 carbon atoms in which at least one hydrogen atom is substituted with a fluorine atom, or a monovalent organic group including —Si(Ra3)(Ra4)O—;
• Ra3 and Ra4 each independently represent an alkyl group, a haloalkyl group, or an aryl group;
• and L20 represents a divalent linking group selected from the group consisting of —O—, —COO—, —OCO—, a divalent aliphatic group, and a combination thereof, and
• wherein the polymerizable group represented by P1 in formula (I) is any polymerizable group selected from the group consisting of groups represented by formulae (P-1) to (P-7),
