Resist composition, method for producing resist pattern and method for producing plated molded article

A resist composition comprising a resin (A1) including a structural unit having a group represented by formula (20), an alkali-soluble resin (A2), an acid generator (B) including a compound represented by formula (b0), and a compound (C) represented by formula (I):

• wherein, in formula (20), Ra1′ and Ra2′ each independently represent a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, Ra3′ represents a hydrocarbon group having 1 to 20 carbon atoms, or Ra1′ represents a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, and Ra2′ and Ra3′ are bonded to each other to form a heterocyclic ring having 3 to 20 carbon atoms together with carbon atoms and X to which Ra2′ and Ra3′ are bonded, a methylene group included in the hydrocarbon group having 1 to 20 carbon atoms and the heterocyclic ring having 3 to 20 carbon atoms may be replaced by an oxygen atom or a sulfur atom, X represents an oxygen atom or a sulfur atom, na′ represents 0 or 1, and * represents a bond:
• wherein, in formula (b0), Rb1 represents a hydrocarbon group having 1 to 18 carbon atoms which may have a fluorine atom, and a methylene group included in the hydrocarbon group having 1 to 18 carbon atoms may be replaced by an oxygen atom or a carbonyl group,
• X represents an oxygen atom or a sulfur atom,
• R01 represents a hydrocarbon group having 1 to 18 carbon atoms, and a methylene group included in the hydrocarbon group having 1 to 18 carbon atoms may be replaced by an oxygen atom, a sulfur atom or a carbonyl group,
• x0 represents an integer of 1 to 6, and when x0 is 2 or more, a plurality of groups in parentheses may be the same or different from each other, and:
• wherein, in formula (I), ring W1 represents a heterocyclic ring having a nitrogen atom as atoms constituting the ring, or a benzene ring having a substituted or unsubstituted amino group, the heterocyclic ring may have a heteroatom other than the nitrogen atom, and the heterocyclic ring and the benzene ring may have a substituent other than the substituted or unsubstituted amino group,
• A1 represents a phenyl group or a naphthyl group, and
• n represents 2 or 3, and a plurality of A1 may be the same or different.
