Abstract
A method for coating an article made of polypropylene with an electrically conductive primer and thereafter electrostatically applying an organic solvent-type overcoat composition to the primer. The electrically conductive primer contains (A) a urethane-modified chlorinated polypropylene which is a mixture or addition reaction product of a chlorinated polypropylene and a polyurethane resin, the chlorinated polypropylene being prepared by chlorinating a homopolymer of propylene or a copolymer of propylene and another olefin monomer, (B) a melamine resin, (C) a polyester resin and (D) an electrically conductive substance such as carbon black, graphite, silver, nickel or copper. The electrically conductive primer has a surface resistivity of up to 1.times.10.sup.8 ohms after the application of the overcoat composition.
