PCT No. PCT/JP97/03657 Sec. 371 Date Apr. 12, 1999 Sec. 102(e) Date Apr. 12, 1999 PCT Filed Oct. 13, 1997 PCT Pub. No. WO98/17736 PCT Pub. Date Apr. 30, 1998A metal surface treatment composition which can improve the corrosion resistance and the tight adhesion to coating films and impart slipperiness. The composition is an aqueous solution, dispersion or emulsion containing both an acrylic resin having nitrogenous heterocycles, amino and/or ammonium groups and hydrophobic groups and a heavy metal or a salt thereof. The amino or ammonium groups have at least one structure selected from among those represented by general formulae (I) (wherein in R1, R2: hydrogen, hydroxyl, substituted or unsubstituted, linear or branched C1-C5 alkyl, or substituted or unsubstituted, linear or branched C1-C5 hydroxyalkyl) and (II) (wherein R3, R4, R5: hydrogen, hydroxyl, substituted or unsubstituted, linear or branched C1-C5 alkyl, or substituted or unsubstituted, linear or branched C1-C5 hydroxyalkyl).
