Abstract
Disclosed is a resin composition comprising the reaction product obtained by reacting an isopropenylphenol and/or its oligomers with a straight-chain unsaturated fatty acid, an unsaturated fat or oil, a polymer of diene hydrocarbon or its derivative having carboxyl or hydroxyl substituents at the ends of the polymer molecule, or a maleinized polymer of diene hydrocarbon and then reacting the resulting intermediate product with a polyhydric alcohol and/or a polybasic acid. When used as a coating and particularly as an undercoating for metals, this resin composition exhibits excellent resistance to corrosion and to water. It may either be directly used as an oil-soluble resin composition or be neutralized with a base prior to use as a water-soluble one.
