Claim:
A thermosetting resin composition comprising an imide oligomer component (A) comprising at least one imide oligomer represented by general formula (1): (wherein R 1 s may be the same or different; R 2 s may be the same or different, and each R 2 s represents a divalent organic group containing at least two aromatic rings; R 3 s may be the same or different, and each R 3 s represents a monovalent organic group selected from —OH and —NH 2 ; R 4 s may be the same or different, and each R 4 s represents a tetravalent organic group containing at least one aromatic ring; V represents a direct bond or a divalent group selected from the group consisting of —O—, —CO—, —O-T-O—, —COO-T-OCO—, —C(CH 3 ) 2 —, and —C(CF 3 ) 2 —; T represents a divalent organic group; a and b independently represent an integer of 0 to 15; a+b represents an integer of 0 to 15; and the compound represented by general formula (1) may be a block copolymer or a random copolymer) or general formula (2): (wherein R 1 s may be the same or different; R 2 s may be the same or different, and each R 2 s represents a divalent organic group containing at least two aromatic rings; R 3 s may be the same or different, and each R 3 s represents a monovalent organic group selected from —OH and —NH 2 ; R 4 s may be the same or different, and each R 4 s represents a tetravalent organic group containing at least one aromatic ring; V represents a direct bond or a divalent group selected from the group consisting of —O—, —CO—, —O-T-O—, —COO-T-OCO—, —C(CH 3 ) 2 —, and —C(CF 3 ) 2 —; T represents a divalent organic group; c is an integer of 1 to 15; d is an integer of 0 to 15; c+d is an integer of 1 to 15; and the compound represented by general formula (2) may be a block copolymer or a random copolymer); and an epoxy resin component (B) comprising at least one epoxy resin; wherein each R 1 represents a divalent organic group selected from the group consisting of the following: general formula (6): wherein each X independently represents a divalent group selected from the group consisting of —C(═O)—, —SO 2 —, —O—, —S—, —(CH 2 ) L —, —NHCO—, —C(CH 3 ) 2 —, —C(CF 3 ) 2 —, and —C(═O)O—, or a direct bond; each R 5 independently represents —OH, —NH 2 , hydrogen, halogen, or an alkyl group having 1 to 4 carbon atoms; and L and s independently are an integer of 0 to 5.
