減する「防眩効果」を殆ど有していない。[Prior Art] Conventionally, a single-layer metal film such as Al or Cr is formed as a reflective film on one side of a transparent substrate made of glass or plastic, etc., which has been commonly used as rearview mirrors and side mirrors for automobiles. '' has almost no ``anti-glare effect'' that reduces the ``dazzle'' of sunlight in the morning and evening or the headlights of following cars at night.

う問題があった。[0004] Mirrors intended for the above-mentioned anti-glare effect exhibit a unique color due to the spectral reflectance characteristics of their multilayer reflective film, and are widely popular because they have excellent decorative properties as well as anti-glare effects. Since the number of layers of the reflective film is as large as 2 to 8, it takes a long time to form the film, resulting in poor productivity and high cost.

In the morning and evening, the sun is low and the angle of elevation relative to the sun is small, so direct reflections of sunlight from side mirrors and the like easily enter the driver's eyes. Furthermore, the light from the headlights of the following vehicle at night is almost at the same height as the driver's eyes, so it is easy to see the driver's eyes when reflected by the rearview mirror or side mirror.

In this case, the headlights of a car behind you feel dazzling at night. Incidentally, the spectral energy of a halogen lamp used in automobile headlights is as shown by the chain line in FIG.

In particular, the wavelength of 500n, which makes the double-layer film back mirror of Example 3 feel dazzling to the eyes.
Since the light in the wavelength range before and after the light of m is extremely efficiently removed from the reflected light, it exhibits an outstanding anti-glare effect.
