  • the glossiness (gloss value) of each test piece was measured before and during the weatherability test, and from the start of the test, the glossiness of the test piece was 80% or less of the glossiness before the weatherability test.
  • the time (h) required for this to occur was defined as the "80% gloss retention time” and was used as an index of weather resistance.
  • the glossiness of the test piece was measured using a gloss meter (manufactured by Nippon Denshoku Industries, VG-2000) at a measurement angle of 60°. The results are also listed in Table 2.
