本発明は光学用のガラスフィルターに関し、特にカラー
写真撮影に最適する紫外線カツト用ガラスフィルターお
よびその製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an optical glass filter, and more particularly to a glass filter for cutting ultraviolet rays that is optimal for color photography, and a method for manufacturing the same.
カラー写真撮影用のフィルターとして、特に被写体のコ

を補正しようとするものである。As a filter for color photography, it is especially important to cut ultraviolet rays with a transmission limit wavelength of 350 to 400 nm and to improve the contrast of the subject.
There is a demand for something that absorbs several percent of light with a wavelength of 0 nm. This is similar to the phenomenon in which human visual sensitivity reaches its maximum at 55 to 560 nm, making yellow and other colors appear bright and red and purple appear dark.This is due to the chromatic sensitivity of color film and the spectral transmission characteristics of photographic lenses. It attempts to correct colors that are not faithful to the reproduction.

This color-developed filter of M colloid absorbs wavelengths of 530 to 570 nm. Furthermore, by using Au and Ce0z together, the thickness of 350 to 400 nm
Although there are commercially available filters that cut ultraviolet rays and meet the required characteristics as the above-mentioned filters for color photography, various problems still remain. For example, Tokko Kokko Showa 47-3
No. 5767 introduces an ultraviolet blocking glass filter containing 20 to 37% by weight of PbO. Further, Japanese Patent Publication No. 54-2647 discloses an optical glass filter containing PbO2 to less than 20% by weight and a method for manufacturing the same. These glasses have the advantage that the color development of the oil colloid is stable in the 7 range, but when Pb is present, the amount of addition of 0.0
When the weight of 015 is less than 2, there is a problem that appropriate colloidal particles are difficult to appear even after reheating treatment. Therefore, the amount of noodles added had to be relatively large (0.002 to 0.05% by weight).
しかしＭの添加量が多くなると成形中や徐冷中に発色し

スト高になる欠点もあった。However, if the amount of M added is large, color develops during molding or slow cooling, and it is very difficult to control the size of M colloid particles by reheating treatment, resulting in poor color stability and other manufacturing problems. There were some difficulties. It also had the disadvantage of high manufacturing costs due to the large amount of candy raw materials used and the large amount of gold added.

Filter glasses containing 0-30% by weight are disclosed. This glass has almost solved the disadvantage of color development before reheating by eliminating the glaze and reducing the amount of Au added, but the base glass is borosilicate glass, so the melting temperature is high. Furthermore, since the transition temperature is high, the heat treatment time required for color development is extremely long.

The object of the present invention is to provide a glass filter having spectral characteristics suitable for a filter for color photography by adding M and CeO2.

外線カツトフィルターを得ることができた。The present invention achieves the above objects by adding 6G BaO to lower the softening temperature, further adding LizO and F to lower the high temperature viscosity, and improving the diffusivity of M. In addition, the amount of additive added is reduced to - to -~ compared to the conventional one, and the reheating color development time is shortened due to the accompanying reduction in the transition temperature. Furthermore, by adding Cent, it was possible to obtain an ultraviolet cut filter having spectral characteristics suitable for the above-mentioned color photography filter, that is, having an absorption peak at 520 to 560 nm and a transmission limit wavelength at 350 to 400 nm. .

After melting the blended composition to have a composition of 0.0015, it is directly molded and slowly cooled, and then the Au in the glass is reheated to develop color. Chemical durability deteriorates due to the relative relationship with
When it exceeds 65%, the melting temperature becomes high and it is difficult to obtain a homogeneous glass.

It hinders the diffusion of color and has a negative effect on color development.

Together with F, the effect of lowering high-temperature viscosity is remarkable, and it has a positive effect on the diffusivity of Au and the growth of colloids for color development, but 0
．． If it is less than 2%, no effect can be expected, and if it exceeds 3%, it not only deteriorates chemical durability but also increases costs. It is preferably in the range of 1 to 3%. Alkali metal oxides are effective components for lowering the melting temperature and obtaining homogeneous glass, but the sum of Na2O, KzO and LizO is %
If it exceeds 17%, the chemical durability will deteriorate, and if it is less than 17%, the melting temperature will increase, and the coloring properties of the M colloid will also be adversely affected. Desirably it is 20 to 23%.

are oxides of divalent metals other than PbO, and are added singly or in combination. In particular, BaO lowers the softening temperature, improves the color development conditions of the Au colloid, and has the effect of improving color saturation. The amount added is desirably 3 to 11%; if the total RO is less than 8%, a good coloring effect cannot be obtained, and if it exceeds 20%, it will adversely affect pink coloring. F, together with LizO, is effective in lowering the high-temperature viscosity and the transition temperature, and helps increase the diffusivity of M and the growth of M colloids, and has a great effect on reducing the amount of particles added.
α５％未満ではその効果が期待できず、２％を越えると
発色に悪影響があり、失透することもある。If α is less than 5%, the effect cannot be expected, and if it exceeds 2%, color development will be adversely affected and devitrification may occur.

Ａｕの残存量を少なくシ、発色を妨げ、１％未満では熱
還元効果が薄過ぎて発色によくない。5nO- has an effect as a thermal reducing agent for Au coloration, but is also effective as a defoaming agent. If the amount added exceeds 4%, the residual amount of Au decreases and color development is hindered, and if it is less than 1%, the thermal reduction effect is too weak and is not good for color development.

If it is less than 3%, no effect can be expected, and if it exceeds 1.5%, the transmission limit wavelength for ultraviolet rays will not only shift too far to the long wavelength side, but will also take on a yellowish tinge.

足りる。Au is used as a coloring agent for pink filters,
According to the present invention, a range of 0.0006 to 0.oois% is sufficient, and if the amount added is more than 520 to 560 nm.
If the amount of absorption is too high and is less than the above-mentioned range, no effect will be exhibited. In the end, only a small amount of addition is needed compared to conventional ones.

ど多くの利点を有する。As explained above, the glass filter and the manufacturing method of the present invention do not use candy raw materials that are expensive and require careful handling, and the gold content is lower than that of conventional products.
In addition to being able to be manufactured by reducing the time to h, the reheating color development time was significantly shorter than that of borosilicate glass. Furthermore, the glass of the present invention has many advantages such as a lower high-temperature viscosity and lower melting temperature, resulting in a higher yield (accompanied by a reduction in manufacturing costs).
