Title:
RED MULTILAYER COATING FILM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/054545
Kind Code:
A1
Abstract:
To provide a red multilayer coating film having high brightness and high saturation. A red multilayer coating film having, in order, a white coating film with an L* value of 80 or higher, a first base coating film having a hue of 1YR-10Y by the Munsell Color System, a second base coating film having a hue of 1R-10R by the Munsell Color System, and a clear coating film, wherein, in a curve obtained from the value SS obtained by multiplying the spectral reflectance by the spectral visual efficiency of photopic vision of the red multilayer coating film, the value at a wavelength of 580 nm is 5% or lower, and the curve has a maximum value of 15% or higher at wavelengths of 590 nm-650 nm. (Where the spectral reflectance is the spectral reflectance of light received at a light receiving angle of 45° with respect to light irradiated from an incident angle of 45° with respect to the normal of the red multilayer coating film on the clear coating film side of the red multilayer coating film.)
