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

[0377] Next, specific examples of the present invention will be described.

[0378] [1] Synthesis of polymer (preparation of polymer solution)

Synthetic example 1

[0380] Into a 1 L reaction vessel equipped with a stirrer, a reflux cooler, a dropping funnel, a nitrogen introduction tube, and a thermometer, 37.6 parts by weight of 1,3-butanediol diacetate as a solvent was added and heated to 90°C. Next, 2 parts by weight of 2,2'-azobis(isobutyronitrile) (AIBN) and 3 parts by weight of 1,3-butanediol diacetate (solvent) were added, and then in the flask, dripping Pump, with about 4 hours, drop and mix 27 parts by weight of (3,4-epoxycyclohexyl) methyl methacrylate (manufactured by Daicel Chemical Industry Co., Ltd., trade name Cyclomer M100), 1.5 parts by weight of methyl 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 drip pump, 5 parts by weight of 2,2' as a polymerization initiator dissolved in 20 parts by weight of 1,3-butanediol diacetate (solvent) was added drop...

Synthetic example 2～8

[0382] The same operations as in Synthesis Example 1 were performed except that the types, usage amounts, and types of solvents of monomer components used in the synthesis of polymers (preparation of polymer solutions) were changed as shown in Table 1. As a result, seven types of polymer solutions (polymer solutions A2 to A8) containing the polymer A were obtained.

Abstract

A color filter ink is adapted to be used to manufacture a color filter by an inkjet method. The color filter ink includes pigments, solvent and a curable resin material, wherein a main pigment including a halogenated phthalocyanine zinc complex, a secondary pigment including a sulfonated pigment derivative, the curable resin material includes a polymer (A) including a epoxy-containing vinyl monomer (a1) as a monomer component and a polymer (B) including the fluoroalkyl- or fluoroaryl-containing vinyl monomer represented by formula (1) as a monomer component. In the formula (1), R5 represents alkyl containing 1 to 7 of hydrogen atom or carbon atom, D represents single key or 2-valent alkyl containing hetero atom, Rf represents fluothane group or fluorine aryl containing 1 to 20 of carbon atom, and z is 0 or 1.

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...
