Problems solved by technology

[0009] However, the wetting spread of the ink after ejection is not necessarily the same
That is, when the inkjet ink for color filters contains C.I. The spread of ejected ink changes, causing color unevenness of pixels

Embodiment 1

[0126] [Production of color filter and display device]

[0127] [Color filter]

[0128] -Preparation of deep color composition for partition wall formation-

[0129] The concentrated color composition K1 can be obtained as follows: First, measure the K pigment dispersion 1, propylene glycol monomethyl ether acetate in the amount shown in Table 1, and mix at a temperature of 24°C (±2°C) , Stir at 150rpm for 10 minutes, then measure the amount shown in Table 1 of methyl ethyl ketone, binder 2, hydroquinone monomethyl ether, DPHA liquid, 2,4-bis(trichloromethyl) -6-[4'-(N,N-bisethoxycarbonylmethyl)amino-3'-bromophenyl]-s-triazine, surfactant 1, at a temperature of 25°C (±2°C) Then, the mixture was added sequentially, and the resulting material was stirred at 150 rpm at a temperature of 40°C (± 2°C) for 30 minutes. In addition, the amounts shown in Table 1 are parts by mass, and are specifically the following composition.

Embodiment 2～4、 comparative example 1～3

[0190] In Example 1, except that the polymerizable monomer in the ink was changed to the polymerizable monomer described in Table 4, a color filter and a liquid crystal display device were produced in the same manner as in Example 1.

[0191] The viscosity of the polymerizable monomer at 25°C was measured using a viscometer (B-type viscometer, manufactured by Toki Co., Ltd.).

Embodiment 5～6

[0194] In Example 1, the pigment dispersion liquid (G1) for G was changed to (G3) or (G5) described in Table 5 below, and (G2) was changed to (G4) or (G6). In the same manner as in Example 1, a color filter and a liquid crystal display device were produced.

[0195] In addition, for PG36 pigment dispersions (G3) and (G5), different batches of G pigment dispersions (G3A) to (G3E) and (G5A) to (G5E) were prepared in the same manner as in Example 1. Color filters and liquid crystal display devices.

Abstract

The present invention provides an int-jet ink liquid for color filter, which can restrain color non-uniform of pixel generated by the difference of the C.I.pigment green 36 (PG36) paint dispersion liquid between various groups. The int-jet ink liquid includes a polymerization monomer containing polymerization group, C.I.pigment green 36(PG36) as pigment and at least a yellow pigment, thereinto, the polymerization monomer ratio is below 1.1 relative to the pigment, the polymerization monomer viscosity is below 700mPa / s under 25 DEG C.

Description

Technical field [0001] The present invention relates to an inkjet ink for a color filter suitable for applying droplets by an inkjet method to form colored pixels, a method for manufacturing a color filter using the ink, a color filter obtained by the method, and The color filter display device. Background technique [0002] In recent years, with the development of personal computers, especially large-screen LCD TVs, the demand for liquid crystal displays, especially color liquid crystal displays, has been increasing. However, because the color liquid crystal display is expensive, the demand for cost reduction is increasing. Especially for color filters with a relatively high cost ratio, the cost reduction requirement is very high. [0003] Such a color filter usually has a coloring pattern of three primary colors of red (R), green (G), and blue (B). The liquid crystal is turned on and off by turning on and off the electrodes of each pixel corresponding to R, G, and B. It works a...
