Abstract:
An anti-reflection colored film-coated glass product prepared by forming on a transparent glass substrate with a refractive index of 1.47-1.53, a high refractive index film with a refractive index of 1.59-2.30 and a film thickness of 80-140 nm and containing 0-85% silicon oxides, 10-95% titanium oxides and 5-30% fine gold particles in terms of weight percentage wherein sum of silicon oxides, titanium oxides and fine gold particles is 90 wt % or more, and by forming on said high refractive index film, a low refractive index film with a refractive index which is a value in the range of 1.35-1.58 and at least 0.20 smaller than the refractive index of said high refractive index film, having a film thickness of 70-99 nm and containing 90-100% silicon oxides in terms of weight percentage.
