成物およびそれを用いた塗膜形成方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a novel coating composition that forms a coating film with excellent cosmetic properties and a coating film forming method using the same.
（従来の技術及びその問題点）
自動車、二輪車等の外板の上塗り仕上げとしては、着色
顔料によるソリッドカラー仕上げ方法と、光ｖｌ壓を示
すメタリック仕上げ方法とに大別できる。(Prior Art and its Problems) The top coating of outer panels of automobiles, motorcycles, etc. can be roughly divided into solid color finishing methods using colored pigments and metallic finishing methods that exhibit a high degree of light.

膜を硬化、乾燥させるのがよい。In the present invention, a colored base coat layer is formed on such a substrate using the coating composition of the present invention, and a clear paint is further applied on the colored base coat layer to form a clear coat layer. The colored base coat layer and the clear coat layer can be formed by, for example, diluting the coating composition of the present invention with thinner to a viscosity suitable for painting, spraying it on the base material, and then baking it. Among these methods, a clear paint for forming a clear coat layer may be spray-painted without baking, and then baking may be performed.Among these methods, spray-painting the coating composition of the present invention onto a substrate and baking the same may be used. It is preferable to adopt the so-called 2-coat 1-bake method in which a clear paint is sprayed to form a clear coat layer without any damage, followed by baking.The spray coating method may be either electrostatic or non-electrostatic. The coating machine may be either a spray gun or a mini-bell type rotary atomizer, but it is preferable to use a non-electrostatic air exposure spray gun. The baking conditions are not different from conventional ones, for example, 12
The coating film is preferably cured and dried by baking at a temperature of 0 to 140 degrees for 20 to 40 minutes.

材上に形成することができる。The amount of the coating composition and clear coating of the present invention to be used is as follows:
Although not particularly limited, the cured dry film thickness of the colored base coat layer is usually about 10 to 30 microns, preferably about 15 to 20 microns, and the effective dry film thickness of the clear coat layer is usually about 20 to 60 microns, preferably is 3
It is preferable to use the above composition so that the thickness is about 0 to 50 microns. If the hiding power of the colored base coat layer formed using the coating composition of the present invention is low, the thickness of the colored base coat layer may be increased, but the base material may be coated with a low lightness of about 05 to 2 on the Munsell scale in advance. If an intermediate coating is applied, even if the thickness of the colored base coat layer is thin, it is effective in hiding the appearance. In addition, the clear coat layer may be formed in two steps by the following method, that is, after coating and baking the clear paint on the colored base coat layer, the clear coat layer may be further coated and baked. In this way, a coating film with excellent image clarity, durability, etc. can be formed on the substrate.

かった。(Effect of the invention) The coating composition of the invention contains a specific titanium nitride and does not contain carbon black, or because the amount of carbon black is minimized, it has no effect on conventional solid color coatings and metallic color coatings. It has no yellowish tinge, and has excellent depth and transparency. A coating film with no yellow tint and excellent depth and transparency could not be obtained with conventional Sonorado colors and metallic colors.
