Problems solved by technology

However, the surfactant described in this document greatly reduces the surface tension of the ink itself, which may impair the ejection stability of the inkjet.
In addition, although it is difficult to predict based on general common sense, the ink described in this document has the problem of reducing the swelling property of tiny liquid droplets injected by the inkjet method.

[0527] [2] Preparation method of colored curable resin composition

[0528] Next, a method for preparing the colored curable resin composition of the present invention will be described.

[0529] In addition, the colored curable resin composition of this invention can be prepared by previously preparing a pigment dispersion liquid, and mixing other components in it, and can also prepare it by mixing all components together. Hereinafter, the case of preparing according to the former method is taken as an example for illustration, but it is not limited thereto.

[0530] First, weigh predetermined amounts of (a) colorant, (c) organic solvent, and (e) dispersant as an optional component when (a) colorant contains pigment, and in the dispersion treatment process, use (a) The pigment in the color material is dispersed to prepare a pigment dispersion liquid. In this dispersing treatment process, the pigment can be micronized by using a Paint Conditioner, a sand mill, a ball mill, a...

Embodiment

[0560] The present invention will be described more specifically with reference to Examples and Comparative Examples below, but the present invention should not be construed as being limited to the following Examples unless the gist is exceeded.

Synthetic example 1

[0561] (Synthesis example 1: corresponding to (e-2) acrylic block copolymer containing nitrogen atoms)

[0562] An acrylic A-B block copolymer having a tertiary amino group was synthesized according to Example 1 of JP-A-1-229014 except that the amino group (dimethylamino group) in the copolymer was not quaternized. The weight average molecular weight Mw of the obtained copolymer was 9000, the amine value was 121 mgKOH / g, and the acid value was 0 mgKOH / g.

[0563] In addition, the amine value is represented by the weight of the KOH equivalent amount per 1 g of solid content after removing a solvent, and it measures it by the following method.

[0564] 0.5 to 1.5 g of the dispersant synthesized above was accurately weighed in a 100 mL beaker, and dissolved in 50 mL of acetic acid. Using an automatic titration device with a pH electrode, using 0.1mol / L HClO 4 The acetic acid solution was used for neutralization titration of the dissolved solution. Using the inflection point of...

Abstract

Disclosed is a colored curable resin composition (ink) which can achieve both of surface smoothness of a pixel and a wet expansion property in a pixel bank in the production of a color filter by an ink-jet technique. Specifically disclosed is colored curable resin composition which comprises at least a coloring material (a), a binder resin (b), an organic solvent (c) and a surfactant (g), wherein a solvent (c-1) having a boiling point of 180 DEG C or higher (as measured under the pressure of 1013.25 [hP]) makes up 80 wt% or more of the total amount of the organic solvent (c), and a 0.02 wt% solution of the surfactant (g) which is prepared with the solvent (c-1) has a surface tension falling within a specified range and a contact angle on a glass substrate falling within a specified range.

Description

technical field [0001] The present invention relates to a colored curable resin composition, a color filter, a liquid crystal display device and an organic electroluminescent display panel. Specifically, the present invention relates to a colored curable resin composition in which a coating film suitable for forming pixels by an inkjet method has flatness and swelling properties in the manufacture of a color filter, and a colored curable resin composition formed using the colored curable resin composition A color filter, and a liquid crystal display device and an organic EL display (organic electroluminescence display) having the color filter. Background technique [0002] In the color filter manufacturing technology, a pixel formation method in which a coloring material (ink) is injected into a pixel bank (that is, a substantially rectangular concave region surrounded by a black matrix) is put into practical use by an inkjet method. [0003] The basic qualities required fo...
