[0161]

[0162] —Preparation of Carbon Black Dispersion (K—1)—

[0163] A carbon black dispersion (K-1) was prepared using the following recipe.

[0164] (Pigment Dispersion K—1)

[0165] ・Carbon black (Nipex 35 manufactured by Dizak Co., Ltd.) 13.1%

[0166] ・Dispersant (compound 1 below) 0.65%

[0167] ・Polymer (random copolymer of benzyl methacrylate / methacrylic acid=72 / 28 molar ratio, molecular weight 37,000)

[0168] 6.72%

[0169] · Methoxypropyl acetate (MMPGAc ＊ Made by Daisy Road Company)

[0172] 【Chemical 2】

[0173]

[0174] The above-mentioned components were mixed and stirred for 1 hour using a homogenizer under the condition of 3000 rpm. Using a bead disperser using 0.3 mm zirconia beads (trade name: dispersion pad, manufactured by GETZMANN), microdispersion treatment w...

Embodiment 2～ Embodiment 4、 comparative example 1～ comparative example 3

[0336] In Example 1, the polymerizable dark color composition coating liquid CK-1 was replaced by the polymerizable dark color composition coating liquid shown in Table 5, and the filter color was produced in the same manner as in Example 1. A liquid crystal display device was produced in the same manner as in Example 1 using the color filter, and an evaluation test of the color filter was performed in the same manner as in Example 1. The results are shown in Table 5.

Embodiment 5

[0338] In Example 4, the relative humidity when the polymerizable dark color composition coating liquid CK-4 was formed on the substrate was replaced with the relative humidity shown in Table 5, and the color filter was produced in the same manner as in Example 4. A liquid crystal display device was produced in the same manner as in Example 4 using the color filter, and an evaluation test of the color filter was performed in the same manner as in Example 1. The results are shown in Table 5. In addition, the evaporation rate of the (mixed) solvent when the evaporation rate of butyl acetate is set to 1 is described in the column of "evaporation rate of solvent in polymerizable composition" in Table 5 (the same applies to Tables 6 to 8).

Abstract

The present invention provides a polymeric composition, a manufacturing method of a color filter with the polymeric composition, the color filter manufactured by the manufacturing method, and a liquid crystal display device with the color filter, wherein the polymeric composition at least comprises the following components: (a) colorant, (b) alkali-soluble resin, (c) polymeric compound with more than three polymeric groups, (d) polymerization initiator, (e) fluorine-containing surfactant, and (f) solvent. When the evaporation velocity of n-butyl acetate is set to 1, the evaporation velocity of the solvent is less than 0.34.

Description

technical field [0001] The present invention relates to a polymerizable composition suitable for producing a color filter, a color filter, a method for producing the same, and a liquid crystal display device. More specifically, it relates to a polymerizable composition in which the evaporation rate of a solvent in the composition is controlled within a specific range, and in a process of applying the polymerizable composition to a substrate, relative to the atmosphere at the time of formation. A method of manufacturing a color filter with humidity controlled within a specific range, a color filter manufactured by the manufacturing method, and a liquid crystal display device including the color filter. Background technique [0002] Conventionally, pigment dispersion methods, dyeing methods, plating methods, and printing methods are known as methods for producing color filters used in liquid crystal display devices and the like. From the standpoints of spectral characteristic...
