Abstract: The relationship between the composition of water soluble acrylic copolymer(WSAC)resin, staining technology and character of the final coloured film have been investigated. It is found that an aqueous solution containing 8%~10% WSAC(Tg 34~39℃)and pigment in 1.1 times its effective concentration was rather reasonable. From this mixture a good corrosion resistant coloured phosphate film was prepared when it was macerated for 15~30 s and dried for 20~40 min at 60~80℃.

Key words: water soluble acrylic copolymer, coloured phosphate film, staining
