つた種類の樹脂が用いられている。(Prior Art) As shown in FIG. 6, a conventional color filter has a structure in which a dyed layer 2 is provided on a transparent substrate 1 made of glass or the like, and three predetermined colors, for example, red R, green G, and blue B, are colored. dyed in color. The dyeing layer 2 is made of a dyeable resin such as gelatin or acrylic resin. A transparent protective film 3 is placed on top of this dyed layer 2.
is coated. This protective film 3 is made of a different type of resin from that of the dyed layer 2, since if it is the same dyeable resin as the dyed layer 2, it will be colored or mixed due to dye migration.
（発明が解決しようとする問題点）
上記従来技術においては、染色層と保護膜とは
異なる材料よりなるので、温度による膨張係数の

しもよくないのではがれやすく、さらに光の屈折
率のちがいにより透過率が下がつたりするという
問題点があつた。(Problems to be Solved by the Invention) In the above-mentioned conventional technology, since the dyed layer and the protective film are made of different materials, they tend to be distorted due to the difference in expansion coefficient due to temperature, and the adhesion is not necessarily good, resulting in peeling. Furthermore, there was a problem that the transmittance decreased depending on the difference in the refractive index of light.

じみや混色がほとんどなくなつた。 An ultraviolet-curable dyeable acrylic resin is applied as a film agent 5 onto a transparent substrate 4 such as glass and dried (FIG. 2). A photoresist 6 is applied thereon and exposed to ultraviolet light using a predetermined mask 7 (FIG. 3). After development, the exposed portion of the film agent 5 is dyed with an acid dye in a predetermined color, for example, red R (fourth step).
figure). Thereafter, photoresist application, partial exposure, development and dyeing are repeated in the same manner, and the film material 5 is dyed in a mosaic with the red R, green G, and blue B to form a dyed layer 8 (FIG. 5). On top of this, the same ultraviolet curable acrylic resin as the film material 5 was applied as a protective film 9, and after drying, the entire surface was irradiated with ultraviolet rays to crosslink and cure the protective film (FIG. 1). In the color filter 10 made in this manner, the protective film 9 is hardened and becomes difficult to be stained with acid dye, and there is almost no color bleeding or color mixing.
（実施例 ２）
透明基板上に可染性樹脂としてゼラチンを膜剤
として塗布し、酸化染料を用いて上記実施例と同
様にして、上記膜剤を赤、緑、青の三色に染め分
けて染色層を形成し、その上に上記膜剤と同じゼ
ラチンを塗布乾燥した。(Example 2) Gelatin as a dyeable resin was applied as a film on a transparent substrate, and the film was dyed in three colors of red, green, and blue using oxidation dye in the same manner as in the above example. A dyed layer was formed, and the same gelatin as the above film agent was applied thereon and dried.
さらに、この後全体を180℃でベークした。こ
のベーキングによりゼラチンの可染性が減じ、色
にじみや混色が少なくなつた。 Furthermore, after this, the whole was baked at 180°C. This baking reduced the gelatin's dyeability, resulting in less color bleeding and color mixing.
（効果）
上述の構成よりなる本発明のカラーフイルタは
染色層と保護膜とが同じ材料であるので、熱ひず
みが生じにくく、密着性もよいのではがれにく
い。またマイグレーシヨンがおこりにくいので、
色にじみや混色が生じることなく。また光の透過
率を高くできる。(Effects) In the color filter of the present invention having the above-described structure, the dyed layer and the protective film are made of the same material, so thermal distortion is less likely to occur, and the adhesion is good, making it difficult to peel off. Also, migration is less likely to occur, so
No color bleeding or color mixing. Also, the light transmittance can be increased.
