Document Type and Number:
Japanese Patent JP7030151
Kind Code:
B2
Abstract:
To provide a composite coating material containing an inorganic luminescent material in which a formed coating layer has very high transmittance in a solar radiation wavelength range and excellent durability, while exhibiting color.SOLUTION: A composite coating material containing an inorganic luminescent material that contains a radiation cooling coating material and an inorganic luminescent material, in which the inorganic luminescent material comprises a light-emitting substrate and an activator doped in a light emitting substrate, and the light emitting substrate has a band gap ≥4 eV, the coating layer formed with the composite coating material has an absorption peak in a visible wavelength region, an average reflectivity of the coating layer formed by the composite coating material with respect to ultraviolet rays in the 300 nm to 400 nm wavelength range is 10% to 20% higher than that of radiant cooling coating layer formed by the radiation cooling coating material relative to ultraviolet rays in the range of 300 nm to 400 nm, a difference between the average reflectance of the coating layer formed by the composite coating material and the radiant cooling coating layer formed by the radiant cooling coating material is - 5% to 5% with respect to sunlight whole wavelength region.SELECTED DRAWING: None
