Abstract:
1. A resin composition comprising a resin obtained by reacting a compound represented by formula (1) and/or (2) with an aldehyde represented by formula (3) and/or (4) in the presence of an acidic catalyst wherein in formulae (1) and (2), X represents a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, or a cyclohexyl group, Y represents an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, or a cyclohexyl group, p represents a number of 1 to 3, q represents a number of 0 to 3, provided that when a plurality of Xs and Ys are present, Xs and Ys may be each the same or different, and A in formula (1) represents a number of 0 to 2, and wherein in formulae (3) and (4), Z represents an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, a cyclohexyl group, a hydroxyl group, a formyl group, or a carbonyl group, r represents a number of 0 to 6, provided that when a plurality of Zs are present, Zs may be each the same or different, and B in formula (3) represents a number of 0 to 2, said resin comprising at least one structure represented by a formula selected from the group consisting of formulas (5), (6), (7) and (8): wherein all of Y, Z, p, q, r, A, and B are the same as described in the formulae (1), (2), (3) and (4), X′ is the same as X in the formula (1) or (2), or a single bond for forming a direct bond with X, Y, Z, or an aromatic ring in the resin, wherein said resin has a carbon concentration of 90 to 99.9% by mass of the resin, an oxygen concentration of 0 to 5% by mass of the resin, and a solubility in propylene glycol monomethyl ether acetate of 10% or more by mass of the resin; and at least one of an acid generator and a crosslinking agent.
