Abstract
This invention provides a process to produce a hydroxyl group-containing ester-forming addition reaction product having an acid value of 20 mgKOH/g or less, which process is characterized in that 2,2-dimethylolalkanoic acid having 6 to 8 carbon atoms is melted, and is then mixed with alkanoic acid monoglycidylester having 8 to 24 carbon atoms so that an ester-forming addition reaction may occur. Thus obtained reaction product contains almost no undesirable high-molecular components, is quite excellent in reactivity and compatibility with a curing agent, and is useful for the manufacture of high-solids paint etc.
