<p>Provided is a thermosetting resin which has benzoxazine rings and which exhibits excellent dimensional stability. Specifically provided is a thermosetting resin having benzoxazine rings, said thermosetting resin containing both a structure (A) represented by general formula (1) and a structure (B) represented by general formula (2). In general formula (1), R1 and R2 are each independently hydrogen or a C1-20 organic group; Y1 is either an aliphatic diamine residue having a straight-chain, branched or cyclic structure or an aromatic diamine residue, each diamine residue having 1 to 20 carbon atoms and optionally containing a heteroatom; n is an integer of 1 to 500; and * represents a binding site. In general formula (2), R3 and R4 are each independently hydrogen or a C1-20 organic group; X is either an aliphatic group having a straight-chain, branched or cyclic structure or an aromatic group, each group having 1 to 20 carbon atoms and optionally containing a heteroatom; Y2 is either an aliphatic diamine residue having a straight-chain, branched or cyclic structure or an aromatic diamine residue, each diamine residue having 1 to 20 carbon atoms and optionally containing a heteroatom; m is an integer of 1 to 500; and * represents a binding site.</p> |
