    摘要: Disclosed is an aqueous metallic coating composition which significantly reduces the production of hydrogen gas and does not have the problems which are brought about from hydrophobic segments. The composition can be stored for a long period of time and provide a metallic coating having good appearance and film properties (e.g. water resistance and adhesive properties with substrates). The aqueous coating composition of the present invention comprises

    (a) an acryl resin having a number average molecular weight of 1,000 to 50,000, an acid value of 15 to 200 and a hydroxyl value of 20 to 200, prepared by copolymerizing an ethylenic monomer and a phosphate monomer represented by
    [wherein X represents a hydrogen atom or a methyl group, Y represents an alkylene group having 2 to 4 carbon atoms and n is an integer of 3 to 30.] and
    (b) a pigment;
       the acryl resin being present in an amount of 2 to 500 parts by weight, based on 100 parts by weight of the pigment.
