Abstract

A copolymer includes a repeating unit represented by Formula (I); and a repeating unit represented by Formula (II), in Formula (I), R 1 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; R 2 represents an alkyl group having 1 to 20 carbon atoms and having at least one fluorine atom as a substituent, or a group including —Si(R a3 )(R a4 )O—; L represents a divalent linking group as defined herein; and R a3 and R a4 each independently represent an alkyl group as defined herein, in Formula (II), R 10 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; R 11 and R 12 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; R 11 and R 12 may be linked to each other; and X 1 represents a divalent linking group.

First claim

What is claimed is:

1. A copolymer comprising:
a repeating unit represented by the following formula (III); and
a repeating unit represented by the following formula (V),

wherein, in the formula (III), R 1 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; ma represents an integer of 1 to 20; na represents an integer of 5 to 7; and X represents a hydrogen atom or a fluorine atom, and

wherein, in the formula (V), R 10 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms: R 11 and R 12 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: R 11 and R 12 may be linked to each other: X 11 represents a divalent linking group comprising at least one selected from the group consisting of —(C═O)O—, —O(C═O)—, —(C═O)NH—, —O—, —CO— and —CH 2 —; and X 12 represents a divalent linking group including at least one linking group selected from —(C═O)O—, —O(C═O)—, —(C═O)NH—, —O—, —CO—, —NH—, —O(C═O)—NH—, —O(C═O)—O— and —CH 2 — and including 2 to 4 substituted or unsubstituted aromatic rings; and a total number of carbon atoms of X 11 and X 12 is 7 or more.

2. The copolymer according to claim 1 , further comprising:
a thermally crosslinking group.

3. A composition comprising:
the copolymer according to claim 1 .
