Description

  The present invention relates to a colored curable composition.

  Colored curable compositions are used for the production of color filters used in display devices such as liquid crystal display panels, electroluminescence, and plasma display panels.

In this colored curable composition, it is known to use a pigment or a dye as a colorant.
Among these, colored curable compositions using pigments generally have high light resistance and heat resistance, but the light transmittance of the color filter is reduced due to the pigment particles. There is a problem that the contrast is lowered (see Patent Document 1).
Further, a colored curable composition using a dye has a feature that the color filter has a high contrast because there is no light scattering by the pigment particles, but there is a problem that the light resistance and heat resistance are low. (See Patent Documents 2 and 3).

  Accordingly, various studies have been made to improve the light resistance and heat resistance of colored curable compositions using dyes. Among them, phthalocyanine dyes having a specific structure and pyridone azo having a specific structure are used for green colored curable compositions. It has been proposed to use a dye in combination (see Patent Document 4).

However, even with the invention described in Patent Document 4, the present inventors still have room for improvement in heat resistance, and the resulting color filter has insufficient solvent resistance. I found out.
An object of the present invention is to provide a new colored curable composition that is excellent in heat resistance and solvent resistance, and that can form a color filter that does not deteriorate contrast and light resistance.

  As a result of intensive studies to find a colored curable composition that can solve the above-described problems, the present inventors include a phthalocyanine dye having a specific structure different from the phthalocyanine dye conventionally known as a colorant. The present inventors have found that a colored curable composition can solve the above problems, and have completed the present invention.

The color difference (ΔEab *) was determined to be 3.6.
As an evaluation standard for color difference, if ΔEab * is 5 or less, almost no hue change is observed, showing good characteristics as a color filter, and if ΔEab * is more than 5 and less than 10, slight hue change is recognized. However, if the color filter has a practically no problem level and ΔEab * is 10 or more, a clear hue change can be confirmed, which is a problematic level for the color filter.

The chromaticity of the colored curable composition film after irradiation was measured, and the color difference before and after irradiation was determined to be 0.6.
As the evaluation criteria for the color difference, as described above, when ΔEab * is 5 or less, there is almost no change in hue, showing good characteristics as a color filter, and when ΔEab * is more than 5 and 10 or less, However, when ΔEab * is 10 or more, a clear hue change can be confirmed, which is a problematic level for a color filter.

[Evaluation 3] Evaluation of solvent resistance The chromaticity of the obtained colored curable composition film was measured using the same colorimeter as described above.
Next, the obtained colored curable composition film was immersed in a large excess amount of propylene glycol monomethyl ether kept at a constant temperature of 23 ° C. for 30 minutes, and the chromaticity of the colored curable composition film after immersion was made the same. The color difference before and after heating was determined to be 1.8.
As an evaluation standard for color difference, if ΔEab * is 5 or less, almost no hue change is observed, showing good characteristics as a color filter, and if ΔEab * is more than 5 and less than 10, slight hue change is recognized. However, if the color filter has a practically no problem level and ΔEab * is 10 or more, a clear hue change can be confirmed, which is a problematic level for the color filter.

[Evaluation 4] Contrast Evaluation When the contrast value of the obtained colored curable composition film was measured using a contrast colorimeter (CT-1; manufactured by Aisaka Electric Co., Ltd.) with a blank value of 10,000, it was 9112. It was.
As a criterion for evaluating the contrast of the colored curable composition film, if the contrast value is 8000 or more, depolarization is hardly recognized, and the color filter exhibits good characteristics, and the contrast value exceeds 6000 and is 8000 or less. For example, a slight degree of depolarization is recognized, but it is at a level where there is no problem in practical use of the color filter. Is a level.
