ABSTRACT:
Water-borne alkyds containing polybasic acids, a sulfonated aromatic acid, or equivalent, e.g., the sodium salt of 5-sulfoisophthalic acid, polyhydric alcohols, and fatty acids, are prepared in a two-step process by first reacting the carboxylic acids and the alcohols until a clear solution is obtained and then adding and reacting the fatty acid to achieve a desired relatively low acid number. These alkyd products are water dispersible without the need for amine stabilization and form protective films on substrates.
