Abstract

PURPOSE: A water-thinnable alkyd resin useful for paints for metallic articles, excellent in hardness, flexibility, rust prevention and water resistance, consisting of sorbic acid, maleic anhydride and an epoxy resin having at least two epoxy groups.
CONSTITUTION: An alkyd resin precursor is obtained from the following three components: (A) an oil or a fatty acid, (B) a polyol and (C) a polycarboxylic acid or its anhydride. Then, this precursor is reacted with the following two essential components: (D) sorbic acid and maleic anhydride and (E) an epoxy resin having at least two epoxy groups in the molecule. In this reaction, if a solvent which is inert to hydroxyl groups and carboxyl groups and dissolves sorbic acid (e.g., dioxane) is added in an amount of 0.1W10wt%, based on the alkyd resin precursor, deposition of unreacted sorbic acid on the upper part of a reaction kettle can be prevetned, and one cause for paint film defects can be eliminated.
