Problems solved by technology

[0009] However, according to the above-mentioned conventional technology, when focusing only on the miniaturization of pigment particles and the contrast of the image, although some improvement effects can be obtained to some extent, in the miniaturized diketopyrrolopyrrole pigments, the use of In the process of making color filters, especially in the case of repeated development, post-baking, and UV cleaning, there is a problem that the surface is dry.

Embodiment 1

[0604] In the present invention (A) diketopyrrolopyrrole pigment, 50 g of Ilgafoared BT-CF (manufactured by Ciba Japan Co., Ltd., Pigment Red 254), 500 g of sodium chloride (average particle diameter: 10 μm) , and 150 g of diethylene glycol (manufactured by Tokyo Chemical Industry Co., Ltd.), which is a water-soluble organic solvent, were put into a stainless steel 1-gallon kneader (manufactured by Inoue Seisakusho Co., Ltd.), and kneaded at 50° C. for 10 hours.

[0605] Next, 25 g of the resin A solution (solid content: 30% by mass) synthesized as above was added to the mixture and mixed, and the mixture was poured into about 3 liters of hot water, and mixed at a high speed while heating to about 70°C. Machine stirring for about 1 hour to make a slurry. Then, filtering and washing with water were performed to remove sodium chloride and the solvent, and drying was performed in a hot air oven at 60° C. for about 24 hours to obtain a surface-treated (A) diketopyrrolopyrrole pigm...

Embodiment 2

[0628] Using the pigment dispersion composition obtained in Example 1 above, a colored polymerizable composition of the following composition (2) was prepared.

[0629] In addition, the red pigment dispersion composition A and the yellow pigment dispersion composition A were prepared as follows.

[0630] (red pigment dispersion composition A)

[0631] In the production method of the above-mentioned treated pigment, it was carried out in the same manner as in Example 1, except that "red pigment ("Cromophored A2B" manufactured by Chiba Japan Co., Ltd.: PR177)" was used instead of "Irgafoaled BT-CF". Salt grinding yielded a treated pigment with a primary average particle size of 28 nm. Then, using the obtained processed pigment, except having used "pigment derivative (5)" instead of "pigment derivative (1)", it carried out similarly to Example 1, and obtained the red pigment dispersion composition A.

[0632] In addition, the yellow pigment dispersion composition A was prepared...

Abstract

The present invention provides a pigment dispersion composition and its production method, a colored polymerizable composition, a color filter and its production method. The pigment dispersion composition of the present invention contains a diketopyrrolopyrrole pigment, and 0.1 to 30 parts by mass of a phthalimide-alkylated diketopyrrolopyrrole with respect to 100 parts by mass of the diketopyrrolopyrrole pigment. Pyrrole, 0.1 to 20 parts by mass of phthalimidoalkylated quinacridone with respect to 100 parts by mass of the diketopyrrolopyrrole pigment, and at least one organic solvent.

Description

technical field [0001] The present invention relates to a pigment dispersion composition, a method for producing the pigment dispersion composition, a colored polymerizable composition containing the pigment dispersion composition, a color filter formed using the colored polymerizable composition, and the color filter Manufacturing method. Background technique [0002] A color filter is a pigment dispersion composition in which an organic pigment or an inorganic pigment is dispersed, which contains a multifunctional monomer, a photopolymerization initiator, an alkali-soluble resin, and other components to form a colored polymerizable composition, and the colored polymerizable composition is used It is produced by forming a colored pattern by photolithography or the like. [0003] In recent years, in the application of liquid crystal display elements (LCD), there is a trend of expanding the use of color filters not only in monitors but also in televisions (TVs). Also began ...
