Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide light-sensitive material suitable for producing a color filter having excellent spectral transmission characteristics of red, green and blue, and particularly excellent in heat resistance and light resistance. The present invention relates to a method for producing a color filter using this. Further, the present invention relates to a silver halide light-sensitive material suitable for easily manufacturing a color filter having a high density black portion and a method for producing a color filter using the same.

[0002]

2. Description of the Related Art A color filter is a color face plate for CRT display, a photoelectric conversion element plate for copying,
Used in filters for single-tube color TVs, flat panel displays using liquid crystals, and color solid-state devices. A commonly used color filter is formed by regularly arranging three primary colors of blue, green and red, but there are some filters having four or more hues as required. For example, a color filter for an image pickup tube or a color filter for a liquid crystal display device requires a black pattern for various purposes.

Regarding a color filter using a silver halide color photographic light-sensitive material, an internal development method (for example, JP-A-63-261361) and an external development method (for example, JP-A-63-261361) are used.
JP-A-55-6342) discloses a color filter. Further, a simpler method for producing a color filter has been studied and disclosed in Japanese Patent Application Nos. 5-302804 and 6-1363. However, in a color filter using a silver halide color light-sensitive material, the cyan couplers and cyan dyes have low heat resistance, and improvements have been desired. Further, in a color filter using a silver halide light-sensitive material, it is desired to make the film thickness thinner, and as a coupler used in the color filter, a 2-equivalent coupler is desired rather than a 4-equivalent coupler.

Japanese Patent Application No. 6-84 describes a patent for a color filter which has improved these problems, that is, a color filter which has improved heat resistance of a cyan coupler and a cyan dye.
Although disclosed in Japanese Patent No. 315, a cyan coupler having higher heat fastness was desired. On the other hand, Japanese Patent Application No. 6-
The hue of the dye obtained from the cyan coupler disclosed in Japanese Patent No. 84315 is short-wave absorption for use in the green-sensitive layer,
Since the saturation of green tends to decrease, improvement has been desired.
As couplers having a longer absorption of dyes obtained, 5-amide naphthol type couplers described in JP-A-61-153640 and EP-161626 are known, and 2-equivalent couplers described therein. Since a lot of stains (thermal stains) generated by thermal decomposition are generated, it causes color turbidity, and improvement is desired.

[0005]

SUMMARY OF THE INVENTION It is, therefore, a first object of the present invention to provide a silver halide light-sensitive material which is excellent in heat fastness and has little color turbidity and which is particularly suitable for preparing a color filter. A second object of the present invention relates to a silver halide light-sensitive material suitable for easily producing a color filter having a high density black portion and a method for producing a color filter using the same. The third object of the present invention is to
LCD that does not require complicated process and is suitable for mass production
It is an object of the present invention to provide a color filter having excellent light transmittance, which hardly causes defects even in the panel manufacturing process.

The protective layer of the above-mentioned color photosensitive material was brought into close contact with the coated surface of the light transmitting substrate. Then the temperature of the contact surface is about 1
Using a laminator whose temperature was set to 30 ° C., the solution was passed at a linear velocity of 0.45 m / min.

Rinsing water Deionized water with conductivity of 5 μS or less

Each of the obtained color filters had RGB with high color density and high spectral transmittance and black stripes of high density. The blue light transmittance of the blue pixel portion of each color filter was measured. Next, place each of the same color filters in an oven at 180 ° C.
After heating for a period of time, the blue light transmittance of the blue pixel portion of each color filter was measured in the same manner. The value (ΔD _B ) obtained by subtracting the value of blue light transmittance before heating from the value of blue light transmittance after heating is shown in the table.

[0113]

[Table 5]

In the color filter using the coupler of Comparative Example in Table 5, it can be seen that the blue pixel portion has a reduced transmittance due to the stain produced by thermal decomposition of the coupler, resulting in color turbidity. On the other hand, it was found that the color filter produced by using the coupler capable of desorbing fluorine of the present invention is excellent in the amount of stain generated by heating. By using the coupler of the present invention, it was possible to obtain a color filter having no color turbidity and excellent spectral transmittance.
