収する特徴を有するためである。As the pearl pigment, mica coated with titanium oxide was used. The use of titanium oxide-coated mica pearl pigments is an important factor in discriminating authenticity by machine reading. Because titanium oxide coated mica is
It has the characteristic that the reflected light when irradiated with light in the visible light region is stronger than that of the substrate, and the titanium oxide absorbs light in the ultraviolet region when irradiated with light in the ultraviolet wavelength region. Because it has.

It is to make it possible to obtain. When a material (metal material, etc.) that reflects light in the visible light region and the reflected light is stronger than that of the base material, a characteristic waveform shape is obtained when the light is irradiated in the ultraviolet region. It is necessary to newly use another material in order to obtain it, which is inefficient when cost is taken into consideration.
