Aluminum, brass, and metallic pigments (A)
Metal pigments such as copper, and those that have been subjected to surface treatment or coating, and those metal powders, pigments that have been subjected to various surface treatments on natural mica or synthetic mica, commonly called pearl pigments, Any pigment that imparts a design property, such as a thin piece prepared by coating a metal or the like, or a small piece of a holographic film can be used. It is also possible to impart a unique design by using two or more of these. As an addition amount, 0.1 to 10% by weight is dry-blended in the paint. If it is less than 0.1% by weight, sufficient brightness cannot be obtained, and if it is more than 10% by weight, there occurs a problem that surface smoothness cannot be obtained.

る。[0006] As the powder coating (B) containing no coloring pigment, the resin system used in ordinary powder coatings can be used in the same manner as the component (C) described later, and the composition differs from the component (C) in composition. Means that no coloring pigment is contained. The same applies to the manufacturing method. The components (B) and (C) can be used in the same resin system or in different resin systems. However, by adjusting the surface tension of the component (B) and the component (C) and adjusting the component (B) lower than the component (C), a design with higher luminance and higher surface gloss can be obtained. For this purpose, different resin systems are used for the component (B) and the component (C) to obtain a difference in surface tension. Alternatively, the adjustment is performed by using a silicon-based or acrylic-based surface tension adjuster as an additive in the composition of the component (B). The amount of the component (B) added is 5 to 90% in the paint.
Dry blend by weight. If the amount is less than 5% by weight, sufficient surface gloss cannot be obtained, and if the amount is more than 90% by weight, a problem that the concealing property of the coating film is deteriorated occurs.
