Epoxy resin represented by formula (1) (a), a compound having both a polymerizable ethylenically unsaturated group and a carboxyl group in one molecule (b), and if necessary, a compound having a hydroxyl group and a carboxyl group in one molecule (c) reacted Reactive polycarboxylic acid resin which is a reaction product of the reactive epoxy carboxylate resin obtained by making and polybasic acid anhydride (d), and the epoxy resin (a'), compound (b) represented by any of formulas (2) to (4), And a reactive polycarboxylic acid resin which is a reaction product of a reactive epoxy carboxylate resin obtained by reacting a compound (c) and a polybasic acid anhydride (d) as necessary. (In formula (1), R 1 may be the same or different, represents a hydrogen atom, a halogen atom, or a hydrocarbon group having 1 to 4 carbon atoms, and n represents an integer of 1 to 10) |
