An anti-glare element provided with a front side substrate comprising a substrate having a wave length selective property, and a back side substrate comprising a transparent substrate and having electrochromic films which exhibit an electrochromic phenomenon interposed between the front side substrate and back side substrate, wherein a photocatalyst film comprising a photocatalyst substance having transmittivity and a hydrophilic functional film comprising a hydrophilic film of a hydrophilic substance are formed on the front side of the front side substrate comprising a substrate with said wave-length selective property, to thereby give an anti-fog function. Or electrode-cum-reflective film is formed on the backside film of the electrochromic film, to thereby achieve a reflective mirror. An anti-glare and anti-fog element or an exterior mirror for automobiles wherein spectral reflectance characteristics of the anti-glare and anti-fog element can be set so that predetermined color phase may be presented at the time of un-operating of an anti-glare function by a substrate having wave length selective property, and along with this surface dirt can be disassembled and economical efficiency and chemical stability are satisfied, can be provided. Also, color phase of the mirrors which have mutually different functions among plurality of mirrors is determined as a predetermined color phase, and the color phase can be set to the same extent, and the combination of the mirror which does not give a sense of incongruity visually can be embodied.

On the surface of a light-transmitting plate material , a transparent metal thin film is provided, and further, on the surface of the transparent metal thin film , a hydrophilic functional layer containing a photocatalytic substance is provided. The hydrophilic functional layer comprises a laminate of, from the side of the transparent metal thin film , a photocatalytic layer containing a photocatalytic substance and a hydrophilic layer containing a hydrophilic substance.

Composite material

A colored anti-fog mirror includes a substrate, a metal reflecting film formed on a front surface of the substrate, and a hydrophilic function layer having a hydrophilic function and containing photocatalytic substance provided on the metal reflecting film. The thickness of the hydrophilic function layer is set in such a manner that wavelength of reflected light has a peak of reflectance within a range from 400 nm to 510 nm and a mirror surface thereby exhibits a bluish color.

Colored anti-fog mirror

An antiglare inner mirror includes a housing which is supported by a stay and is capable of inclining by an inclining device. A mirror main body is mounted on a front opening portion of the housing. The mirror main body includes a front glass, a hologram element and a seal glass bonded integrally together. A reflecting film is formed on the rear surface of the seal glass. The hologram element consists of a reflecting type hologram element having a reflecting plane made of interference fringes which is arranged non-parallel to the front surface of the hologram element. Incident light from outside is reflected both by the reflecting film and by the interference fringes of the hologram element to form rays of light reflected in different directions.

An anti-fog element includes a transparent substrate such as a glass substrate, a transparent film of a photocatalyzer such as TiO.sub.2 catalyzing a photocatalytic reaction on the transparent substrate, and a film of a transparent porous inorganic oxide such as SiO.sub.2 formed on the film of the photocatalyzer and having a surface exhibiting a hydrophilic property. Organic matters etc. deposited in openings of the porous inorganic oxide film are dissolved and removed by a photocatalytic reaction caused by light excitation of the photocatalyzer film whereby the anti-fog property of the anti-fog element can be maintained over a long period of time.

Anti-fog element

A vehicle mirror has a mirror housing and a mirror assembly provided in the mirror housing. The mirror assembly includes a glass substrate and a reflecting film made of chromium or aluminum and formed on the back surface of the glass substrate. A panel heater is bonded by adhesive to the back surface of the reflecting film. A hydrophilic film is formed on the front surface of the glass substrate. The hydrophilic film is made of a hydrophilic oxide film such as SiO.sub.2 and functions to spread a waterdrop deposited on the mirror surface in the form of a thin water film.

Vehicle mirror

A waterdrop repellent mirror provide a vibration plate which piezoelectric oscillator is affixed on the back side of the mirror, and a heater is placed therein to heat up the mirror surface. The piezoelectric oscillator on the rear surface of the mirror give ultra sonic wave vibration to the mirror through the vibration plate. When mirror surface resonate by inputting the vibration of the oscillator to the mirror, any waterdrop sticked on the mirror surface are dispersed. Re-sticked fine mist of waterdrop or frozen frost on the mirror surface can be removed by heated up the mirror, thereby clear mirror surface can be secured.
