PURPOSE:To remarkably enhance the decorative effect by forming an electrically nonconductive masking film on a plated film and carrying out painting by electrodeposition to form a paint film only on the electrically conductive part of the plated film not covered with the masking film. CONSTITUTION:The surface of plastics is subjected to catalytic activation, electroless plating and electroplating. An electrically nonconductive masking film is formed on the required part of the resulting plated film and painting is carried out by electrodeposition. A paint film is formed only on the electrically conductive part of the plated film not covered with the masking film, so the remaining part covered with the masking film and the paint film have different colors.
