ある。(Background of the Invention) As disclosed in Japanese Patent Application Laid-Open No. 55-25067, a color filter manufacturing method involves forming a photosensitive resin film for chromosomes on a substrate, and selectively applying this resin film in a predetermined pattern. After exposure and development, the unexposed part is dissolved and removed, leaving only the exposed part of the chromosome. After dyeing this part, the surface is modified to make it resistant to staining, and then a photosensitive resin film is formed again. The pattern is exposed and developed, and the unexposed areas are dissolved and removed.
There is a method of manufacturing a multicolor color filter by dyeing this new pattern of chromosomes and repeating this process.

すむ恐れがあることがわがった。In this production method, it was found that when the surface is modified at a temperature higher than the dyeing temperature, the dye dissolves from the surface modification, and as a result, the color of the surface modification once dyed becomes lighter. Furthermore, even if dyed chromosomes are surface-modified for dyeing resistance, if they are immersed in the next dye bath at a temperature higher than the surface modification temperature, the dyeing resistance will be weakened and the surface-modified material will deteriorate. It has been discovered that the dye in the dye bath may enter the chromosomes, causing the color of the chromosomes to become dull.

のカラーフィルタが形成された。(Description of Examples) To explain with reference to the attached drawings, in step A, a photosensitive chromosome (resin film) 2 such as gelatin is coated on a glass substrate 1 to form a color filter structure. Only the necessary portions of the chromosomes 2 of the color filter manufacturing 1 structure are exposed to light through an exposure mask and developed. In step B, the unexposed portion is dissolved and removed to form a predetermined pattern of chromosomes. In step C, the color filter structure is dyed with an aqueous dye solution at a dyeing temperature of 80°C to dye the chromosome 2, and then washed with water and dried. In the process, this color filter structure is subjected to resist dyeing treatment at a temperature of 7
0°C acetic acid tannic acid aqueous solution (tannin MO, 1w
t%, vinegar MO, 5wt%) for 1 minute, and rinsed with water. Next, 0.1 potassium antimonyl tartrate at 70°C
After immersing the color filter side 3t in the vit% aqueous solution for 1 minute, it is washed with water and dried. Drying is carried out at a temperature of 150° C. for 30 minutes. In this way, the surface of the chromosome dyed in the first color is modified, no dissolution of the dye is observed, and the dye has resistance to subsequent dyeing. ■In step E, the photosensitive chromosome (resin film) 6 is again provided, and only the necessary portions are exposed and developed in a predetermined pattern.In step F, the unexposed portion is dissolved and removed to form the chromosome in the predetermined pattern. Leave 7. ■
In Step G, a second color dyeing process is carried out using a red dye aqueous solution at a dyeing temperature of 60'C to obtain a second (!!) red color filter section 8. Next, in Step 1, the process is carried out. Similarly, the resist dyeing process was treated with an acetic acid tannic acid aqueous solution at a temperature of 50°C for 1 minute, and after washing with water, was treated with an antimonyl potassium tartrate aqueous solution at a temperature of 50°C for the same 1 minute, followed by surface modification treatment by washing with water and drying. In step I, a photosensitive chromosome (resin film) 10 for the third color is formed.At this time, the first color blue is obtained. There was no dullness in the color of the color filter part, and no dissolution of the dye from the red color filter part of the second color was observed.In step J, the third color was dyed as described above. The treatment is completed with a green dye aqueous solution at a temperature of 40°C, but the temperature of the third color dyeing (40'C)
) is lower than the temperature for surface modification of the second color. In the figure,
Reference numeral 11 indicates a patterned chromosome, and reference numeral 12 indicates a third color filter section. In this way, three clear color filters were formed.
