PURPOSE:To provide the title coating film which prevents marine organisms from depositing on the parts of steel structures such as vehicles, marine structures, etc., said parts being in contact with sea water, by applying insulating paint contg. an org. high-molecular compd. as a binder and then applying paint contg. a specified insoluble electrical conductor. CONSTITUTION:Not less than 50% [based on the volume of the component (b)] at least one member (a) selected from the group consisting of graphite powder, carbon black, magnetite, MnO2 and platinum metals is added to paint (b) contg. at least one member selected from the group consisting of an epoxy resin, an unsaturated polyester resin, an acrylic resin, a phenolic resin and a urethane resin as a matrix resin to obtain paint (B). Insulating paint (A) contg. an org. high-molecular compd. as a binder is applied to the part of a steel structure such as a vehicle, a marine structure, etc. to form a coating film of 200mu or above in thickness, said part being brought into contact with sea water. The component B is then applied to said part to form the title coating film. The coating film allows sea water to be electrolyzed by using the whole surface of the part of the steel structure in contact with sea water as an anode.
