Abstract
There is disclosed a process for producing water-dilutable coating compositions by subjecting a reaction mixture containing a phenolic resin and either a drying or semi-drying oil and an alpha, beta-ethylenically unsaturated carboxylic acid anhydride, or an adduct thereof, and a secondary or tertiary amine catalyst, to an elevated temperature for a period of time sufficient to produce a ternary adduct. Said ternary adduct is reacted with water and neutralized to produce a water-dilutable coating composition. The application also discloses a one-stage reaction for the production of a ternary adduct of tung oil, alpha, beta-ethylenically unsaturated carboxylic acid anhydride, and phenolic resin.
