Problems solved by technology

However, when the concentration of the pigment is high, the pigment has a certain particle size and scatters light, so there is a problem that the contrast of the color filter formed using the colored photosensitive resin composition containing the pigment is low.

Embodiment

[0203] Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples. "%" and "part" in an example are % by weight and a part by weight, unless otherwise indicated.

Synthetic example 1

[0205] 15 parts of sulforhodamine (Sulhorodamine) B (manufactured by Kanto Chemical Co., Ltd.), 150 parts of chloroform and 9.8 parts of N, N-dimethylformamide were dropped into a flask with a cooling tube and a stirring device, and maintained under stirring. Below 20°C, 12.0 parts of thionyl chloride was added dropwise. After completion of the dropping, the temperature was raised to 50°C, and the temperature was maintained for 5 hours to react, and then cooled to 20°C. While maintaining the cooled reaction solution at 20° C. or lower with stirring, a mixed solution of 13.9 parts of 2-ethylhexylamine and 24.5 parts of triethylamine was added dropwise. Then, stirring was carried out at the same temperature for 5 hours to make it react. Next, after distilling off the solvent in the obtained reaction mixture with a rotary evaporator, a small amount of methanol was added and vigorously stirred. This mixture was added to a mixed solution of 375 parts of ion-exchanged water while ...

Synthetic example 2

[0208] In the flask with cooling tube and stirring device, drop into 15 parts of pigments shown in formula A0-2 (manufactured by Zhongwai Huacheng), 150 parts of chloroform and 7.1 parts of N, N-dimethylformamide, while maintaining at 20 Below ℃, 8.7 parts of thionyl chloride were added dropwise. After completion of the dropping, the temperature was raised to 50°C, and the temperature was maintained for 5 hours to react, and then cooled to 20°C. A mixed solution of 10 parts of 2-ethylhexylamine and 17.7 parts of triethylamine was added dropwise while maintaining the cooled reaction solution at 20° C. or lower with stirring. Then, stirring was carried out at the same temperature for 5 hours to make it react. Next, after distilling off the solvent in the obtained reaction mixture with a rotary evaporator, a small amount of methanol was added and vigorously stirred. This mixture was added to a mixed solution of 375 parts of ion-exchanged water while stirring to precipitate crys...

Abstract

A coloring light-sensitive resin composition contains colorant (A), adhesive resin (B), optical polymeric compound (C), optical polymeric initiator (D) and solvent (E), wherein the colorant (A) contains organic solvent dissoluble dye with a compound represented by formula (I), and organic pigments.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition suitable for forming a colored image constituting a color filter used in a liquid crystal display element or a solid-state imaging element, and a color filter using the colored photosensitive resin composition . Background technique [0002] In recent years, high-definition, high-brightness, and high-contrast color filters are desired. In order to meet these requirements, with the development of high color purity of color filters, the pigment concentration in the colored photosensitive resin composition has changed. high tendency. However, when the concentration of the pigment is high, the pigment has a certain particle size and scatters light, so there is a problem that the contrast of a color filter formed using a colored photosensitive resin composition containing the pigment is low. [0003] Therefore, specifically, for example, it is disclosed that a pyrazole-based squar...
