Even if it can be classified as window glass, etc. Even if the visibility correction filter for the G1 VTR camera has a large difference between the visibility of the G1 human and the sensitivity of the photoelectric conversion element (solid-state image sensor), the color correction is classified as ζ. Color correction is also necessary for the color of the bright light source at the shooting location. In recent years, near-infrared cut filters, ultraviolet cut filters and red (R),
Even if color correction is performed using three color filters, green (G) and blue (B), the 10th and 10th images are the same as the 11th and 12th figures. .

る。Problems to be Solved by the Invention The problems of conventional color filters are listed as follows: Organic film, printed film, electroplated filters, etc. all use organic substances as binders for dyes or pigments. The color is easily faded by ultraviolet rays, and when dye is used as a coloring agent, the dye itself will fade due to ultraviolet rays because the binder has no UV blocking effect.
As a result, the absorption wavelength peak changes over time. To prevent this, filters are covered with chemically stable materials such as crystal or quartz, or housed in a vacuum to ensure long-term reliability of the filter. Since glass filters are colored by the metals or metal ions they contain, there is almost no fading due to ultraviolet rays.As shown in Figure 12, the glass filter holder 28
is required. Next up Absorption The degree of freedom in arbitrarily controlling the peak of the transmitted wavelength is smaller compared to filters that use organic dyes or pigments. In addition, vapor deposited filters are time-consuming to manufacture and have a limited range of optical properties such as absorption wavelength.

いて説明する。Means for Solving the Problems The Present Invention Table 4 A color filter consisting of an inorganic gel or glass matrix on both sides or one side of a substrate and a dye or pigment present in these matrices. A color filter characterized in that a colored inorganic gel or glass matrix film is formed by supporting on a substrate a liquid in which either an organic dye or a pigment is dissolved or dispersed in an alkoxide or mercaptide solution and then heating the film to form a colored inorganic gel or glass matrix film. According to the present invention, color filters containing organic dyes or organic pigments in an inorganic gel or glass matrix that undergoes minimal structural deterioration due to ultraviolet rays will not fade due to the ultraviolet rays of the filter itself. 4! Since the organic dye or organic pigment serves as the coloring species, the degree of freedom in selecting the wavelength peak of transmitted light is very large. Before detailed explanation, technical points of the present invention will be explained.

ができる。The filter of the present invention is composed of a gel or glass matrix 2 on a transparent glass or plastic substrate 1 and a dye or pigment 3 uniformly dispersed in the gel or glass matrix 2. In particular, when a dye is used as a coloring species, the dye is dissolved in an elemental alkoxide solution and then dried or heated to form a film (dehydration condensation).The distribution of organic dyes and organic pigments in the film obtained is at the atomic level. Since the matrix of this film is made of inorganic gel or glass, it has much higher weather resistance than using an organic binder such as gelatin in the matrix.It also has a high resistance to fading due to ultraviolet rays. It can be made smaller by making the composition UV cuff F-resistant.

A solution containing pyridinium (4'-methylaminophenyl) and terpineol as a thickener was supported on one side of a transparent acrylic plate having a thickness of m+n by screen printing. Thereafter, it was dried at 60°C for 60 minutes to form a gel film (Example-8). Although it exhibits absorption and transmits light of other wavelengths well, this filter can be used for visual sensitivity correction.In other words, for the standard ratio luminous efficiency function V (λ) shown by the dotted line in Figure 7, , it is possible to correct the specific luminous efficiency curve (indicated by the solid line) that deviates toward the high sensitivity side at 620 nm.In this way, it is also effective for applications where the purpose is to utilize absorption only at specific wavelengths (as shown in the implementation). Example 9) It is also possible to control the specific absorption wavelength by mixing multiple dyes. The transmittance curve of a color filter obtained by coating a glass substrate on a glass substrate is the transmittance curve of a color filter obtained by coating a glass substrate with a mixture of the D liquid and the E liquid. In this way, the absorption wavelength can be controlled by using a liquid mixture of multiple dyes with different absorption wavelengths, and the 4D liquid filter and E
The same effect can be obtained even if the liquid filters are stacked one on top of the other.
