Publication number: 20240018365Abstract: A multilayer coating film includes a lustrous layer containing a luster material and a colored layer containing a reddish coloring agent, and having translucency. Regarding a Y value of an XYZ colorimetric system calibrated with a standard white plate, when a light incident angle is 45°, Y(5°) represents a Y value of reflected light measured at a light receiving angle of 5°, and Y(15°) represents a Y value of reflected light measured at a light receiving angle of 15°, the lustrous layer satisfies the following: Y(5°) is 30 or more to 700 or less; Y(15°)=k×Y(5°) (where k is a coefficient); and k is 0.01 or more to 0.3 or less. The concentration of the reddish coloring agent in the colored layer is 1 mass % or more to 17 mass % or less.Type: ApplicationFiled: October 22, 2021Publication date: January 18, 2024Applicant: MAZDA MOTOR CORPORATIONInventors: Takakazu YAMANE, Keiichi OKAMOTO, Kouji TERAMOTO, Ryuji NONAKA, Kazuteru TAMAI, Eiichi KAWASE, Tomohiro FUJIMOTO, Takayoshi NAKAMOTO

Publication number: 20230415454Abstract: A multilayer coating film includes a lustrous layer containing a luster material and a blackish coloring agent, and a colored layer containing a reddish coloring agent, and having translucency. A slope of a tangent of a spectrum of a spectral transmittance, defined as an absolute value, of the colored layer at the wavelength of 620 nm is 0.02 nm?1 or more and 0.06 nm?1 or less, the spectral transmittance being obtainable by dividing a spectral reflectance measured for the colored layer stacked on the lustrous layer at the light receiving angle of 15° in the case of the light incident angle of 45°, by a spectral reflectance measured for the lustrous layer from which the colored layer is removed and a surface of which is therefore exposed, at the light receiving angle of 15° in the case of the light incident angle of 45°.Type: ApplicationFiled: October 22, 2021Publication date: December 28, 2023Applicant: MAZDA MOTOR CORPORATIONInventors: Takakazu YAMANE, Keiichi OKAMOTO, Kouji TERAMOTO, Ryuji NONAKA, Kazuteru TAMAI, Eiichi KAWASE, Tomohiro FUJIMOTO, Takayoshi NAKAMOTO
