(Tato ALM) 0.2 g and 30 g of mineral spirits were removed and dispersed in a ball mill for 24 hours in a pot mill with a diameter of 5 cm and an internal volume of 500 cc inserted with 500 g of lmm diameter glass beads. Thereafter, 42.8 g (30 g as metal content) of commercially available aluminum paste (Toyo Aluminum Co., Ltd. TCR3040) and 30 g of mineral spirit were added to the pot mill, and the ball mill was dispersed for another hour. The obtained slurry was washed with 500 g of mineral spirits to separate it from glass beads and then filtered to obtain a primary colored aluminum pigment.

- Example 1 1-6 Comparative Example 1-11
- Surface-treated steel sheet (JISG33) prepared by using the colored flake pigment obtained in 2 and preparing a paint composition having the following composition and electrodepositing a cationic electrodeposition paint for automobiles.
- Two-coat, one-bake, air-spray coating compositions for the electrode coat and intermediate coating were applied in a two-coat, one-bake method, and baked at 140 ° C for 30 minutes to create a metallic coating film. .
- the thicknesses of the colored base coat layer and the talya coat layer after curing and drying were 20 ⁇ m and 40 ⁇ m, respectively.
- Thermosetting acrylic resin (solid content) 80 parts
- Thermosetting acrylic resin (solid content) 80 parts
- Table 1 shows the results of a five-point evaluation (numerically high, better) of the obtained coated plate in terms of saturation and appearance (clearness).
- the weather resistance of the obtained coated plate was tested with a super xenon accelerated weather resistance tester (Super Xenon Weather Meter SX75 manufactured by Suga Test Instruments Co., Ltd.) for 1000 hours, and the degree of color change was measured with a color difference meter ( Table 1 also shows the results of evaluation using the color difference of Minolta Co., Ltd. “CR300” (the square root of the sum of the squares of the difference between the L *, a *, and b * values of the coated plate before and after the test). Shown in.

- Example 5 5 3 0.5
- Example 1 2
- the coating composition containing the colored flake pigment according to the present invention was applied. Compared with Comparative Example 3 and Comparative Example 4, the coating film has no fading, and the coating film weather resistance is significantly better than Comparative Example 3 and Comparative Example 4. From these results, by using the coating composition containing the colored flake pigment of the present invention, it is possible to achieve both good coating color saturation, coating film appearance and excellent weather resistance. Power S component is struck.
