Specifically, a test piece was placed on a white calibration plate, subjected to reflected color measurement using the SCI method (including normal reflected light) with a light source of D65 and a viewing angle of 10°, and L*, a*, b*, and YI were calculated from the obtained tristimulus values X, Y, and Z. The obtained L*, a*, b*, and YI values are shown together in Tables 26 to 41. Furthermore, the appearance of the test pieces was evaluated by visually observing the light from a fluorescent lamp (manufactured by Panasonic Corporation, Hf fluorescent lamp, model number FHF32EX-N-H) through the test pieces. Specifically, the color tone of the fluorescent lamp light observed through a test piece was compared with the color tone of the fluorescent lamp light observed directly without passing through the test piece, and when no difference between the two could be perceived, it was determined to be “Acceptable”, and when a difference between the two could be perceived, it was determined to be “Unacceptable”. As a result of this evaluation, the appearance of the test pieces prepared from the resin compositions of Examples 130 to 244 were all determined “Acceptable”.
