More Information
Summary:An object of the present invention is to reversibly change a color on a surface of an object using a photochromic substance. A photochromic substance (3) is laminated on a surface portion (1) of an object. The surface of the laminated photochromic substance (3) is irradiated with lights (5) in the ultraviolet wavelengths to cause the photochromic substance (3) changes its color based on a photochromic mechanism. In addition, a wavelength cut-off agent (4) that can block wavelengths of the ultraviolet contained in natural light and illumination light is coated on the laminated photochromic substance (3).
