PURPOSE:To obtain the subject composition having low-temperature curability as well as long-term stability, giving a coating film having excellent corrosion resistance, usable also for electro-deposition coating and useful as a corrosion- proof primer of a metallic material by using a hydrazine group-containing resin and an ester group-containing compound as main components. CONSTITUTION:The objective composition is composed mainly of (A) a hydrazine group-containing resin (preferably a reaction product of epoxy resin and hydrazine and/or monosubstituted hydrazine) and (B) an ester group-containing compound (preferably an alkyl ester of an alpha,beta-unsaturated dicarboxylic acid and/or its condensate with a polyhydric alcohol). A resin composition for water- base baking paint is produced by neutralizing the above composition with an acid and dispersing in water. |
