Problems solved by technology

However, the dispersion stability of the zinc complex compound of halogenated phthalocyanine in the ink is poor, and when the color filter ink containing the zinc complex compound of halogenated phthalocyanine is used to form the colored part, It is difficult to prevent the occurrence of color unevenness, density unevenness, etc. stably for a long period of time
In addition, in the case of using a color filter ink containing a halogenated zinc complex of phthalocyanine, it is difficult to make the droplet discharge stability sufficiently excellent.

Embodiment

[0363] Next, specific examples of the present invention will be described.

[0364] [1] Synthesis of polymer (preparation of polymer solution)

Synthetic example 1

[0366] Add 37.6 parts by weight of 1,3-butanediol diacetate as a solvent (solvent) to a 1L reaction vessel with a stirrer, reflux cooler, dropping funnel, nitrogen introduction tube, and thermometer, and heat to 90°C . Next, add 2 parts by weight of 2,2'-azobis(isobutyronitrile) (AIBN) and 3 parts by weight of 1,3-butanediol diacetate (vehicle), and then pour into the flask by dripping The pump was used for about 4 hours to instill and mix 27 parts by weight of (3,4-epoxycyclohexyl) methyl methacrylate (manufactured by Daicel Chemical Industry Co., Ltd., trade name Cycroma-M100), 1.5 parts by weight of 2-(0-[1'methylpropyleneamino]carboxyamino)ethyl acrylate (manufactured by Showa Denko Co., Ltd., trade name MOI-BM), 1.5 parts by weight of 2-hydroxyethyl methacrylate (HEMA )The solution. On the other hand, using another infusion pump, 5 parts by weight of 2,2' as a polymerization initiator dissolved in 20 parts by weight of 1,3-butanediol diacetate (vehicle) was instilled ov...

Synthetic example 2～10

[0368] In the synthesis of the polymer (preparation of the polymer solution), the type, usage amount, and type of the solvent (solvent) of the monomer components used in the synthesis of the polymer were changed to those shown in Table 1. operation. As a result, nine types of polymer solutions (polymer solutions A2 to A10) containing the polymer A were obtained.

Abstract

The present invention provides a color filter ink adapted to be used to manufacture a color filter having ejecting stability and excellent dispersion stability of pigments. The color filter ink includes a main pigment, a secondary pigment, a solvent and a curable resin material. The main pigment includes halogenated phthalocyanine zinc complex. The secondary pigment includes a sulfonated pigment derivative. The curable resin material includes a first polymer and a second polymer. The first polymer includes an epoxy-containing vinyl monomer as a monomer component. The second polymer includes an alkoxysilyl-containing vinyl monomer represented by a formula (1) as a monomer component. In the formula (1), R1 represents alkyl containing 1 to 7 of hydrogen atom or carbon atom, E represents single key or 2-valent alkyl, R2 and R3 represent alkyl containing same or different carbon atom number of 1 to 6 or alkoxyl containing 1 to 6 of carbon atom, R4 represents alkyl containing carbon atom number of 1 to 6, x is 0 or 1 and y is an integer from 1 to 10.

Description

technical field [0001] The present invention relates to an ink for a color filter, an inkset for a color filter, a color filter, an image display device and an electronic instrument. Background technique [0002] Color filters are generally used in liquid crystal display devices (LCD) and the like that perform color display. [0003] In the past, color filters were manufactured using the so-called photolithography method described below. A coating film composed of a material (colored layer-forming composition) is then subjected to photosensitive treatment for irradiating light through a photomask, development treatment, and the like. In such a method, a coating film corresponding to each color is usually formed on almost the entire surface of the substrate, only a part of it is cured, and most of the other parts are removed, and these operations are repeated so that the colors do not overlap, thereby producing a color filter. piece. Therefore, only a part of the coating f...
