The water-soluble amino-alkyd baking paint was developed by amino resin and alkyd resin. The properties of water-soluble amino-alkyd baking paint are better than solvent-borne amino-alkyd baking paint. The influene of acid value, hydroxyl value, oil-length, amino-resin, neutralizer, co-solvents and the structure of resins on the synthesis and application properties of water-soluble alkyd resin were discussed. The water-soluble alkyd amino baking paint can be compatible with water-borne alkyd anti-corrosive primer, which has outstanding anti-corrosive property. The system can be widely used in industrial fields of automobiles, home appli－ ances, iron,foundry, and so on.
