Abstract The cationic acrylic resin used for electrodepostion was synthesized. The factors affecting the resin water-solubility and properties of the film were studied. The results show that the acrylic copolymer water-solubility based on amine group and was determined by amine content. The active monomer with hydroxyl, the molecular weight and its distribution of the copolymer, neutralizer and cosolvent also affect the resin water-solubility. The composition and ratio of the copolymer, crosslinking agent and conditions of curing have a great effect on properties of the film.
