Claim 10:
11. A bank comprising:
a repeating unit represented by a formula (3-1) and a repeating unit represented by a formula (3-2A):, , wherein R3-1 represents a hydrogen atom, a fluorine atom, or a methyl group; R3-2 represents a hydrogen atom or a C1-C6 linear, C3-C6 branched, or C3-C6 cyclic alkyl group; R3-3 and R3-4 each independently represent a fluorine atom, a C1-C10 linear, C3-C10 branched, or C3-C10 cyclic alkyl group, or a C1-C10 linear, C3-C10 branched, or C3-C10 cyclic fluoroalkyl group; and one or more of R3-1, R3-3, and R3-4 are fluorine atoms or the fluoroalkyl groups,, , wherein R3-5 and R3-6 each independently represent a hydrogen atom or a methyl group; W3 is a divalent linking group and represents —O—, —O—C(═O)—, —C(═O)—O—, —O—C(═O)—NH—, —C(═O)—O—C(═O)—NH—, or —C(═O)—NH—; A3-1 and A3-2 are divalent linking groups and each independently represent a C1-C10 linear, C3-C10 branched, or C3-C10 cyclic alkylene group in which one or more hydrogen atoms in the alkylene group may be substituted by hydroxy groups or —O—C(═O)—CH3; Y3-1 and Y3-2 are divalent linking groups and each independently represent —O— or —NH—; n represents an integer of 1 to 3; and r represents 0 or 1.
