Title:
COLORED ANTIFOG MIRROR
Document Type and Number:
Japanese Patent JP2014202759
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce color tone shift due to a change in a visual line angle while improving durability to a water-repellent car washing agent in a colored antifog mirror formed of a surface coated mirror that has blue-based or green-based reflection color and an antifog property.SOLUTION: A colored antifog mirror 11 has a structure in which a reflective layer 14, a reflectance adjusting layer 20, a photocatalyst layer 16, and a hydrophilic layer 18 are sequentially laminated on the surface of a base material 12. The photocatalyst layer 16 is composed of TiOwith the film thickness of 140-200 nm. The hydrophilic layer 18 is composed of a porous SiO. The reflectance adjusting layer 20 is composed of, for example, a mixture of AlOand TaO, a mixture of AlOand SnO, or a mixture of AlOand ZrO. A maximum value of the reflectance of the colored antifog mirror 11 is in the wavelength of 430-560 nm and the reflection color is a blue-based or green-based color. A ratio of the maximum value to a minimum value of the reflectance of a visible light range of the colored antifog mirror 11 is 2 or more and 4 or less.
