The production technology of the condensation of polybasic acids with polyols matured in the mid-19th century. In 1921, General Electric Company conducted an in-depth study on the reaction of glycerol-phthalic anhydride. It was found that if the phthalic anhydride moiety was replaced by a monobasic acid, the product would have better flexibility and solubility. In 1927, General Electric Company Kienle developed phthalic acid-glycerides of unsaturated fatty acids, whereby alkyd resins were used in coatings. Based on the synthesis of alcohols and acids, the polymer was called "alkyd." ". China's alkyd resin first began in 1947-1948, and Mr. Chen Tiaojun from Yongming Paint Factory began to produce alkyd resin - the launch of "Sanbao Paint".
