Abstract:
The titanium materials of the present invention have an oxide film on the surface and an interference color of the oxide film. In forming a transparent coating layer on the surface of the titanium materials, provisions are made so that the oxide film has an thickness of 150 nm to 600 nm, or the interference color due to the anodic oxide film is developed by the actions of both wavelengths strengthened and weakened by interference and the color phases of the color developed by the wavelength strengthened by interference and that of complementary colors of the color developed by the wavelength weakened by interference are as close to each as not more than 90 degrees apart on the color wheel, or the L* value on the L*a*b* calorimetric system is not less than 33. The laminated glasses of the present invention having excellent ornamentality comprise at least said titanium sheet interposed between multiple sheet glasses layered together by means of adhesive layers.
