Abstract
PURPOSE: An addition reaction product from a polybutadiene with a specific number-average molecular weight, a natural drying or semi-drying oil, an ethylenically unsaturated carboxylic acid and phenol is condensed with formaldehyde to produce said resin for forming coating films with low backing temperature, high hardness and high resistance to water and erosion.
CONSTITUTION: An addition reaction product from 100W5% of a polybutadiene with a number-average molecular weight of 250W10,000, 0W95% of a natural drying or semi-drying oil, an ethylenically unsaturated carboxylic acid or its anhydride, preferably maleic anhydride and an alkyl group-substituted phenol is, after subjected or not subjected to the reaction with an alcohol or primary amine, condensed with formaldehyde in the presence of an amine, ammonia, or an alkaline catalyst to effect methylolation. The resulting water-soluble resin is used as a cold drying coating, forced drying coating, baking coating or electro-depositing coating resin by making the use of the resin property that it cures by the oxidation of the double bonds with oxygen in the air.
