When a metal plate (foil) such as a plate and a resin such as ABS are molded and processed, the aluminum plate is defective (blurred,
It is difficult to confirm the defective portion inside the molding when a pinhole or the like occurs. For this purpose, a coating composition containing copper powder is previously coated on the surface of an aluminum plate to form a coating film containing copper powder, which is then resin-molded and then irradiated with X-rays from the outside to apply X-rays to the copper. BACKGROUND ART A copper powder-containing coating composition is used as a coating for forming an auxiliary film that detects a defective portion of an aluminum plate by allowing a powder-containing coating film to absorb the absorbed X-ray with a measuring instrument.
