Problems solved by technology

However, even pigments are known to have poor light resistance when they are miniaturized to increase brightness. For such pigments, it is necessary to improve light resistance while maintaining the characteristics of high transparency and high color purity.

preparation example Construction

[0082] -Preparation of pigment dispersion composition-

[0083] The preparation method of the pigment dispersion composition of the present invention is not particularly limited, for example, by using a vertical or desktop sand mill, nail mill, slit mill (slit mill), ultrasonic disperser, etc., with a particle size of 0.01 The pigment dispersion composition of the present invention is obtained by finely dispersing the pigment, the pigment dispersant, and the solvent with ~1 mm beads formed of glass, zirconia, or the like.

[0084] Two-roll mill, three-roll mill, ball mill, trommel, disperser, kneader, two-way kneader, homogenizer, mixer, single-screw or twin-screw extruder can also be used before bead dispersion. Kneading and dispersing treatment is carried out while applying strong shear force.

[0085] In addition, details about kneading and dispersion are described in "Paint Flow and Pigment Dispersion" by T.C. Patton (Journal of John Wiley and Sons Co., Ltd., 1964).

Abstract

The invention provides a coloring photosensitive composition, a color filter using the coloring photosensitive composition, and a liquid crystal display device provided with the color filter, the coloring photosensitive composition comprises (A) a colorant provided with a phthalocyanine frame, (B) a solvent, (C) a polymerizable monomer, (D) an adhesive resin, (E) a photopolymerizable initiator, and (F) a polymerizable compound.

Description

technical field [0001] The present invention relates to a colored photosensitive composition having excellent light resistance and developability / solvent resistance while maintaining the characteristics of high transparency and high color purity of a colorant, and a colored photosensitive composition containing the same in a colored pattern A color filter for objects, a method for manufacturing the color filter, and a liquid crystal display device. Background technique [0002] In the past, in small liquid crystal display devices such as mobile phones, mobile game machines, and PDAs, it was necessary to use a backlight light source with a limited capacity such as a secondary battery or a dry battery, so as a colorant for the color filter used in these display devices, It has been advantageous to use a colorant that has high transparency and can transmit bright lines of a backlight well to display colors. [0003] In recent years, the increase in size of liquid crystal displ...
