Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明はカラーテレビ、その他のカラー表示装置に使
われるカラーフイルタの製法に関するものである。The present invention relates to a method for manufacturing a color filter used for a color television and other color display devices.
従来のカラーフイルタの製法として、樹脂に着色剤と光
感受性の硬化剤とを添加したものをガラス基板に塗布

タを製造する方法が提案されている（特開昭57−16407
号）。As a conventional color filter manufacturing method, a method of manufacturing a predetermined color filter by coating a glass substrate with a resin to which a colorant and a light-sensitive curing agent have been added, and subjecting this to pattern exposure and development has been proposed. (JP-A-57-16407
issue).
上記従来のカラーフイルタの製法においては、樹脂に着
色剤が溶けにくく、濃い色が出せないとか、樹脂に着色
剤と光感受性の硬化剤とを添加してかくはんしているう
ちに、樹脂が暗反応などで硬膜されてパターニングがで
きなくなる、といつた問題があつた。In the above conventional color filter manufacturing method, the colorant is difficult to dissolve in the resin and a dark color cannot be obtained, or the resin is dark while the colorant and the light-sensitive curing agent are added and stirred. There was a problem that the film was hardened due to reaction and the patterning could not be performed.
この発明は上記従来の技術における問題点を解決するも
ので、可染性樹脂溶液にこの樹脂を染めることのできる

パターニングが確実に行なえるカラーフイルタの製法を
提供するものである。This invention is to solve the problems in the above-mentioned conventional techniques, and to add a dye capable of dyeing this resin to a dyeable resin solution, and after stirring, add a photosensitive film to form a colored film agent. It is intended to provide a method for producing a color filter which is stable in color and has a strong color and can be reliably patterned.

のカラーフイルタをつくつた（第１図）。なおこれらの
工程はすべてイエロールーム内で行つた。A green acid dye was added to a gelatin aqueous solution and ultrasonically stirred, and then ammonium dichromate was added as a light-sensitive curing agent to obtain a colored film agent 1. This was applied to the glass substrate 2 and dried (Fig. 2). Then, this was pattern-exposed and the non-exposed portion was eluted with a developing solution to form a green color filter pattern G and baked (third step).
Figure). Then, color filter patterns R and B were similarly formed with red and blue dyes, respectively, to produce color filters of three colors of green, red and blue (Fig. 1). All these steps were performed in the yellow room.
出来たカラーフイルタは色が濃く、パターン切れの良い
良好なものであつた。The color filter produced was dark and good with good pattern cutting.
比較例として、ゼラチンに光感受性硬化剤の重クロム酸
アンモニウムを加えて水に溶かしたものに染料を加える
従来の方法では、かくはん中に暗反応が進み、塗布後パ
ターニングしようとしても現像できず、パターン切れが
悪かつた。As a comparative example, in the conventional method of adding a dye to a solution prepared by adding ammonium dichromate as a light-sensitive curing agent to gelatin and dissolving it in water, a dark reaction proceeds during stirring, and development cannot be performed even when trying to pattern after coating The pattern was broken.
もう一つの比較例として、ゼラチン水溶液に重クロム酸
アンモニウムと染料を同時に加えてかくはんした場合に
おいても、パターン切れはあまりよくなかつた。As another comparative example, even when ammonium dichromate and a dye were simultaneously added to an aqueous gelatin solution and stirred, the pattern breakage was not so good.
なお上述の実施例において、ゼラチン水溶液に染料を添
加してかくはんする際、加熱状態でおこなうと染料がよ
く溶けて樹脂との結合もよくなり良好なカラーフイルタ
が得られる。In the above-mentioned Examples, when the dye is added to the aqueous gelatin solution and stirred, if the heating is carried out, the dye is well dissolved and the bond with the resin is improved to obtain a good color filter.
本発明によれば可染性樹脂溶液と染料とを十分時間をか
けてかくはんすることができるので、可染性樹脂溶液に
染料をよく溶かすことができ、また暗反応が生じないの
で、パターン切れの良いカラーフイルターが得られる。According to the present invention, since the dyeable resin solution and the dye can be stirred for a sufficient time, the dye can be well dissolved in the dyeable resin solution, and a dark reaction does not occur. You can get a good color filter.
