となり、金属の特長を発揮できない。However, it is a simple and preferable method to clean the above-mentioned outer wall surface, but it takes time and cost to set up the scaffold, and if the number of times is large, scratches on the cosmetic surface are caused. Also, peeling of the coating film occurs. In addition, the above-mentioned cannot be expected to change the decorative surface and has a finished surface similar to the glass surface, and cannot exhibit the characteristics of metal.

It means the comparison of the lightness difference (ΔL) after 0 hour. Also,
In Examples 1 and 2, the difference in performance is shown in (a) the area ratio of the concave pattern 3 and the convex pattern 4, (b) each hydrophilic coating film 10,
It is presumed to be the non-staining functional difference of the water-repellent coating film 11.

果がある。As described above, according to the stain resistant outer wall material of the present invention, the degree of stain on the decorative surface can be greatly improved. It can also have sufficient weather resistance. It has the self-cleaning power to remove stains by the "compatibility" and "repelling" of rainwater due to the synergistic effect of the characteristics of the hydrophilic coating film and the water-repellent coating film. Dirt adhering to the concave pattern will be made to be a beautiful surface by popping up or popping out by familiarizing with rainwater. Since the hydrophilic coating film is hydrophilic, it absorbs a small amount of moisture, static electricity is less likely to be charged, and dust is less likely to adhere to the hydrophilic coating film. There are characteristics and effects.
