A latent additive which is represented by general formula (1). (In the formula, A represents a five-membered or six-membered aromatic ring or heterocyclic ring; each of R 1 and R 2 independently represents a hydrogen atom, a halogen atom, a cyano group, a hydroxyl group, a nitro group, a carboxyl group, an optionally substituted alkyl group having 1-40 carbon atoms, an aryl group having 6-20 carbon atoms, an arylalkyl group having 7-20 carbon atoms or a heterocyclic ring-containing group having 2-20 carbon atoms; and R 4 represents an alkyl group having 1-20 carbon atoms, an alkenyl group having 2-20 carbon atoms, an aryl group having 6-20 carbon atoms, an arylalkyl group having 7-20 carbon atoms, a heterocyclic ring-containing group having 2-20 carbon atoms or a trialkylsilyl group.) |
