<p>PROBLEM TO BE SOLVED: To improve the shielding property and to decrease the total film thickness by using a solid color liquid coating material containing a thermosetting resin compsn. and a color-coated metal powder as a color coating material. SOLUTION: A color coating material and a clear coating material are applied in wet-on-wet processes and heated so that the twolayered coating film is simultaneously crosslinked and hardened to obtain a multilayered film. The color coating material used forms a coating film with a solid color tone and consists of a solid color liquid coating material containing a thermosetting resin compsn. and a color-coated metal powder. The metal powder consists of aluminum, copper, stainless steel. etc., and has about 3 to 7μm average particle size. The powder is preferably a scale-like powder considering the shielding property. The color metal powder is obtd. by coating the surface of each metal powder particle with a color pigment by the thickness to shield the particle surface. By incorporating the color metal powder, the film thickness of the coating film enough to shield can be decreased to about 5 to 15μm.</p> |
