Title:
眼鏡フレーム及び該眼鏡フレームへの光触媒無機酸化金属膜形成方法
Document Type and Number:
Japanese Patent JP5424130
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a spectacle frame including fibrous ultrafine particles of photocatalytic inorganic metal oxide which allows light to be diffusely reflected, glossiness to be enhanced with amplified diffused reflection due to a large specific surface area, glossiness to be brightened due to the thin thickness, high hardness, and smooth surface; adheres tightly to a highly curved rod body such as a spectacle frame with high density and hardness so as to prevent film separation; causes no tarnish due to the small addition amount of SiO; and improves color tones and glossiness of the spectacle frame of a different color which can be maintained for a long period.SOLUTION: At least titanium oxide as an inorganic metal oxide contained in a liquid photocatalyst is formed of fibrous ultrafine particles. The inorganic metal oxide photocatalytic film containing the titanium oxide fixed to a spectacle frame substrate surface has a film thickness of about 5 nm to 2 μm, a film hardness by pencil test of about 3H or higher, and a gloss retention equal to or higher than 80% for about 10 years.
