Then, at viewpoint A, an interference color based on the phase difference shown by the formula t+(n+-nz) can be observed, and at viewpoint B, if the apparent thickness of the optically anisotropic film 5 is t2, then the formula t
Different interference colors based on z(n+-nz) can be observed.

However, in order to obtain a large retardation, use both polarizing films 4.
The polarization axes of the optically anisotropic film 5 may be perpendicular or parallel to each other, and the polarization axes of the optically anisotropic film 5 may be obliquely intersected at 45 degrees.

フィルムとする。It is common to use an iodine-containing polyvinyl alcohol film as the polarizing film 4.6, but it deteriorates due to heating during the formation of laminated glass, and its function cannot be maintained sufficiently.
In addition, it is not suitable because it has the disadvantage of being easily degraded by moisture.On the other hand, polyvinyl alcohol films containing dichroic dye polarizing elements such as disazo and trisazo compounds are not suitable for heat and moisture. It is suitable because it has resistance to and is not affected in any way by heating at around 100° C. during the formation of laminated glass, which will be described later. These polarizing films are made into polarizing films by laminating a film of triacetate, polyethylene, polyester, or the like as a support on one or both sides thereof.

う利点を有する。In particular, when polyester, such as polyethylene terephthalate, is used as the support, it has the advantage of supporting and reinforcing the weak polarizing film during laminated glass formation, while also adhering extremely well to the ethylene vinyl acetate adhesive layer.

Ｏ□を含有せしめるのが好ましい。The glass plate is generally made of commonly used soda-lime glass, but it may also be made of other component types such as aluminosilicate glass.
Either colorless or colored transparent glass can be used. In particular, soda-lime-based glass plates are convenient because they are inexpensive and easily available, and have the effect of blocking sunlight in the far ultraviolet region and suppressing the deterioration of polarizing films and optically anisotropic films and skin discoloration caused by this. be. In addition, in soda lime glass, CeO, Ti is used to block ultraviolet rays including the near ultraviolet region.
It is preferable to contain O□.

合がよい。Similarly, in order to protect the polarizing film and the optically anisotropic film from heat rays, a metal film or a metal-containing film is formed on the inner surface of both glass plates 2.8 and the outer surface of the circularly polarizing film 4.6. It is even more convenient to provide an infrared ray blocking layer by adhering or the like.

It is preferable to apply

エチレンビニルアセテートはそのような弊害はない。As the adhesive layer 3.7, a polarizing film 4.7 is used for adhesion.
An ethylene vinyl acetate-based adhesive layer that does not have an adverse effect on the optically anisotropic film 6 or the optically anisotropic film 5 and is effective in blocking ultraviolet light is recommended. For example, polyvinyl butyral, which is often used in laminated glass, is bonded to the glass plate and the film 4.6 at a temperature of 130°C or higher, but at this temperature the film shrinks and the polarization and birefringence properties of the film are However, the ethylene vinyl acetate used in the present invention does not have such a problem.

There are those that can be heated and bonded, those that are made by saponifying ethylene vinyl acetate, and those that are modified by introducing carboxylic acid into it and then heated and bonded.The latter has particularly good adhesion to glass and polyester films. In addition, if a material with a melting point of about 70 to 100°C, measured from the bending point in a known thermal expansion test, is selected, it can be bonded at a low temperature of 100°C or less in a short time, and it can be used for polarizing films and optical aberrations. It does not impair the properties of the directional film at all, and does not cause any adverse effects such as shrinkage of these films.
On the other hand, it also has good heat resistance, with no deterioration observed in the boiling heat resistance test of known laminated glass.

The optically anisotropic film 5, for example 5
If the birefringence difference between films a and 5b is different, different interference colors will be exhibited, and if the film 5b has a sloped thickness as shown in the figure, band-shaped multicolor interference colors can be observed.
Also, by changing the viewpoint, the color tone changes, making it rich in elegance. Note that the optically anisotropic film 5 may be appropriately arranged in stripe-like, pattern-like, etc. pieces.

It is. Furthermore, the outdoor glass plate 2 contains CeO to block ultraviolet rays, and an infrared ray blocking layer 2b made of a metal thin film is formed on the inner surface of the glass plate 2. Deterioration of the film 5 and skin discoloration can be suppressed over a long period of time.
