    摘要: Provided are coating composition containing an organic polymer particle (A) composed of an organic polymer having a hydroxyl group and a cationic group in a molecule, the weight average particle size of which being 10 to 35 µm, and a base resin (B), wherein the content of the organic polymer particle (A) is 0.5 to 5.0% by weight in the solid content of the coating composition, and a method of producing the same, and a coating film and underwater structure using the coating composition. The base resin (B) has a group represented by the following general formula (1):

            -COO-M-OCO-A     (1)

    (wherein, M represents a divalent or higher valent metal, and A represents an organic acid residue of monobasic acid) or a group represented by the following general formula (2)

            -COO-Si(R 1 R 2 R 3 )     (2)

    (wherein, R 1 , R 2 and R 3 , which may be the same or different, represent an isopropyl group or an n-butyl group) in a side chain, or has a cross-linking structure represented by the following general formula (3):

            -COO-M-OCO-     (3)

    (wherein, M represents the same meaning as described above).
