８２７３号公報参照）。(Prior Art) Conventionally, for example, when painting a so-called two-tone car in which the upper and lower parts of the car body surface are painted in different colors, the paint surface of the entire car body is first subjected to a chemical conversion treatment A, and then , Electrodeposition coating B and baking treatment a, then intermediate coating C and baking treatment, the first top coat D is applied to either the upper or lower part of the car body, and then this is baked. A method is adopted in which the remaining car body parts are painted in a color different from the first coat with a second topcoat E, and this is baked.
) is common (for example,
(See Publication No. 8273).

ソリッドの場合である。(Problems to be solved by the invention) Depending on the combination of paint colors in conventional two-tone specification cars,
Some methods could not be implemented due to poor adhesion. In other words, the combination is that the first top coat is a color base and a clear coat applied using a wet-on-wet method.
This is a case where the first coat is a bake-type metallic and the second top coat is a solid.

とを特徴とするものである。(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems in the conventional painting method for two-tone specification cars. The method is characterized in that a first top coat of a metallic paint is applied and baked, and then a second top coat of a two-tone solid paint is applied and baked in a top coat booth.
本発明方法は、第１回目がメタリックであって、第２回

増やすように改善されたものである。The two-tone metallic paint used in the present invention is a mixture of a conventional color base and a clear color in order to improve the adhesion between the paints.For example, an acrylic melamine resin one-coat one-bake type metallic paint can be mentioned. This paint has been improved to improve the throwing effect, which increases the adhesive area, and to increase the number of polar groups such as carboxyl groups and hydroxyl groups that strengthen the bond with other paints. .
尚、本発明に使用されるツートン用ソリッド系塗料は、
通常のソリッド系塗料であればよい。The two-tone solid paint used in the present invention is
Any ordinary solid paint will suffice.

After that, spray polyester resin intermediate paint on the outside surface, then spray gray polyester resin paint inside the engine compartment etc., and after a suitable setting time.
Baked and dried. The pre-painting treatment was completed by cleaning this car body with white gasoline etc. at the entrance of the top coating booth.
