Embodiment

[0348] Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited thereto.

Synthetic example 1

[0350] (Synthesis of P-1 of Polymer A)

[0351] 27.0 g of the aforementioned M-6, 126.0 g of MMA, 27.0 g of MAA, and 420.0 g of 1-methoxy-2-propanol were introduced into a three-necked flask replaced with nitrogen, and were mixed with a stirrer (Shinto Scientific Co., Ltd.: three- one motor) and heated while blowing nitrogen into the flask to raise the temperature to 90°C. 1.80 g of 2,2-azobis(2,4-dimethylvaleronitrile) (V-65 manufactured by Wako Pure Chemical Industries, Ltd.) was added to the flask, followed by heating and stirring at 90° C. for 2 hours. After 2 hours, 1.80 g of V-65 was further added, and after heating and stirring for 3 hours, a 30% by mass solution of polymer P-1 was obtained. Measurement was performed by gel permeation chromatography (GPC) under the following conditions using polystyrene as a standard substance. Moreover, it titrated using sodium hydroxide, and the acid value with respect to solid content was 99 mgKOH / g. These measurement methods are ...

Synthetic example 2

[0370] (Synthesis of P-2 and P-3 of Polymer B)

[0371] Into a 500 mL three-necked flask, 160.0 g of ε-caprolactone and 18.3 g of 2-ethyl-1-hexanol were introduced, stirred and dissolved while purging with nitrogen. Add 0.1 g of monobutyltin oxide and heat to 100°C. Eight hours later, after confirming the disappearance of the raw materials by gas chromatography, it was cooled to 80°C. After adding 0.1 g of 2,6-di-t-butyl-4-methylphenol, 22.2 g of 2-methacryloyloxyethyl isocyanate was added. After 5 hours, the disappearance of the raw material was confirmed by H NMR, and then cooled to room temperature to obtain 200 g of a solid monomer (A-5). Monomer (A-5) was confirmed by H NMR, IR, and mass analysis.

[0372] The obtained monomer (A-5) is a monomer mentioned as a preferable specific example of the monomer represented by the said general formula (i), (ii) or (i)-2.

[0373] 37.5 g of monomer (A-5), 5.0 g of monomer M-11, 7.5 g of methacrylic acid, 1.3 g of dodecyl mercaptan...

Abstract

Provided is a pigment dispersion composition capable of creating a color filter with a high contrast. The color filter rarely undergoes surface roughening during the processing steps thereof such as development, post-baking, and UV cleaning, and thus can attain excellent display performance. Further, the pigment dispersion composition exhibits high dispersion stability. A pigment dispersion composition which comprises both organic pigment fine particles and a high-molecular compound having pigment-adsorbing groups, wherein the organic pigment fine particles are build-up pigment fine particles which are prepared by a precipitation process of mixing a solution of an organic pigment in a good solvent with a poor solvent which is compatible with the good solvent and acts as a poor solvent for the organic pigment.

Description

technical field [0001] The present invention relates to a pigment dispersion composition containing buildup pigment particles, a colored photosensitive resin composition using the pigment dispersion composition, an inkjet ink for a color filter, a photosensitive resin transfer material, and a pigment dispersion composition using the pigment dispersion composition. Pigment dispersion composition, colored photosensitive resin composition, inkjet ink and photosensitive resin transfer material for color filter and liquid crystal display device. Background technique [0002] In recent years, high-quality and expanded applications of image-related precision instruments such as color imaging devices and color liquid crystal display devices have been rapidly developed. As a reflection of this, for color filters, there has been an increasing demand for improvement in display performance typified by contrast. From such a point of view, with regard to color materials of color filters,...
