[0259] Each photosensitive coloring composition was evaluated by the following method. The results are shown in Table 3.

[0260] (Pattern formation of filter section and black matrix)

[0261] Each photosensitive coloring composition was spin-coated on a 10 cm×10 cm glass substrate, and then prebaked at 70° C. for 15 minutes using a clean oven to remove the solvent from the photosensitive coloring composition. Thus, a coating film having a thickness of about 2 μm was obtained. After cooling the substrate to room temperature, apply 25 mW / cm to the coating film through a photomask 2 The illuminance is irradiated with ultraviolet light for exposure. As an ultraviolet source, an ultra-high pressure mercury lamp is used. As a photomask, the thing provided with the pattern area for linearity and development tolerance evaluation, and the pattern area for resolution evaluation was used. Here, the pattern area for evaluation of linearity and development resistance is an area in w...

Abstract

The invention provides a photosensitive colored composition and a color filter using the composition capable of realizing high developing tolerance and high image dissection even though the dye content is high or the film thickness is large. The photosensitive colored composition comprises a dye, a transparent resin, a photo-polymerization compound, at least one photo-polymerization initiator represented by any one of the formula (1) to (3).

Description

technical field [0001] The present invention relates to a photosensitive coloring composition, for example, a photosensitive coloring composition that is particularly useful for the formation of red, green, and blue filter segments, black matrices, and the like of color filters used in liquid crystal display devices or solid-state imaging elements. . Moreover, this invention relates to the color filter formed using this photosensitive coloring composition. Background technique [0002] The color filter is formed by arranging two or more kinds of fine band-shaped filter segments with different hues on a transparent substrate such as a glass substrate in parallel (stripe) or intersecting with each other, or two or more kinds of different hues. The fine filter segments are arranged in order in each of the vertical and horizontal directions. The filter segment has a small size of several micrometers to several hundreds of micrometers, and each hue is neatly arranged in a presc...
