PURPOSE:To remarkably enhance the decorative effect by removing part of a plated film to expose the surface of plastics under the part and by carrying out painting by electrodeposition. 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 the remaining part of the plated film not covered with the masking film is removed to expose the surface of the plastics under the part. After the masking film is stripped, painting is carried out by electrodeposition. A paint film is formed only on the electrically conductive part where the plated film is present, so the exposed plastic part and the paint film have different colors. |
