Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter and a method for manufacturing the same. Particularly, the present invention relates to a method for easily producing a color filter having excellent heat resistance.

[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,
It is used for filters for single-tube color televisions, flat panel displays using liquid crystals, color solid-state imaging devices, and the like. Commonly used color filters are red,
The three primary colors of green and blue are regularly arranged and arranged, but there are also those which have four colors or other hues as required. For example, in a color filter for an image pickup tube or a color filter for a liquid crystal display device, a black pattern (black matrix) is required for various purposes. red,
Specific arrangement methods for green and blue include a mosaic, stripe, and delta arrangement, which can be selected as needed.

Conventionally known methods for producing a color filter include a vapor deposition method, a first-in-first-out method, a printing method, a pigment dispersion method, an electrodeposition method, and a resist electrodeposition transfer method. However, the color filters obtained by these methods have drawbacks such as requiring a complicated manufacturing process, easily causing pinholes and scratches, low yield, and low accuracy.

In order to solve these disadvantages, an external developing method using a silver halide color light-sensitive material (for example, Japanese Patent Laid-Open No.
No. 5-6342) and an inner die developing method (for example,
1488952 and 62-71950) were studied.

When a color filter produced by these methods is used in, for example, a color liquid crystal display device or the like, it is generally necessary to use a color filter in a post-process such as vapor deposition of a transparent electrode and coating of an alignment film.
Temperatures above 0 degrees are forced and often the dyes need to be robust.

A cyan coupler capable of forming a dye having such characteristics is described in JP-A-7-294714. However, even when such a coupler was used, it was found that although the dye in the color-developed portion was strong, coloring (stain) caused by the coupler occurred in the uncolored portion after heating at a high temperature. This coloring lowers the color purity of each pixel and narrows the range of hues that can be reproduced as a display device. Such a coupler is generally used in a blue color portion of a color filter due to its spectral characteristics. Therefore, the coloring of the uncolored portion affects the red-colored portion and the green-colored portion, but since this coloring is a hue from yellow to magenta, the color purity of the green-colored portion is particularly reduced. In order to prevent the above phenomenon, it has been desired to suppress the occurrence of this coloring.

[0007]

Accordingly, a first object of the present invention is to provide a method for manufacturing a color filter which does not require a complicated manufacturing process. A second object of the present invention is to provide a method for producing a color filter in which a coloring matter in a coloring portion is robust after heating at a high temperature and unnecessary coloring does not occur in a non-coloring portion.

[0008]

The object of the present invention has been attained by the following inventions. 1. On a support, a photosensitive material containing at least one of a cyan coupler, a magenta coupler and a yellow coupler and having at least three silver halide emulsion layers having photosensitivity at mutually different wavelengths is pattern-exposed, and color development is performed. In a method for producing a color filter having a pixel pattern by performing a treatment and a desilvering treatment, the cyan coupler contains at least one compound represented by the following general formula (1) as a cyan coupler, and further comprises the following general formula (2) and / or A method for producing a color filter, comprising at least one compound represented by the general formula (3).
