Abstract
An adhesive electrostatic coating is applied on a resin molding without substantially affecting the color and the physical properties by the method which comprises the steps of mixing with a resin a complex of a polyether and an electrolyte salt soluble in the polyether, molding the mixture, treating the resultant molding with plasma and then spray-coating an electrically charged paint on the surface of the treated molding. The polyether is selected from the group consisting of alkylene oxide polymers and copolymers, preferably selected from the group consisting of polymers of alkylene oxide having not less that 4 carbon atoms and block or random alkylene oxide copolymers containing not less than 10 weight % of at least one alkylene oxide unit having not less than 4 carbon atoms.
