Tests were conducted on the following items. The test results are shown in Table 'tS3, and in each of the Examples in which a paint with a film thickness of 5 μm and an ultraviolet transmittance of less than 5% was coated, there was no difference in quality even after 1000 hours of weather resistance testing. Note that even in Comparative Example 4, in which an ultraviolet absorber was blended instead of channel black, there was almost no effect of preventing paint film peeling.
