Problems solved by technology

[0004] However, existing pigment dispersion systems tend to cause problems such as scattering due to coarse pigment particles and increased viscosity due to poor dispersion stability. In many cases, it is difficult to further improve contrast and brightness.

[0302] [Manufacturing Method of Colored Curable Composition]

[0303] The colored curable composition of the present invention can be prepared by mixing the above-mentioned components and optional optional components.

[0304] In addition, when preparing the curable colored composition, each component constituting the curable colored composition may be prepared at one time, or may be sequentially prepared after dissolving and dispersing each component in a solvent. In addition, there are no particular restrictions on the order of charging or operating conditions at the time of blending. For example, the composition can be prepared by dissolving and dispersing all the components in a solvent at the same time, and if necessary, two or more kinds of solutions and dispersions of the components can be prepared in advance, and these can be mixed at the time of use (at the time of coating) And prepared into composition.

[0305] The colored curable composition prepared as described...

[0484] After irradiating the colored film with a xenon lamp at 200,000 lux (lux) for 10 hours (corresponding to 2 million lux·h), the chromaticity change, that is, the ΔEab value was measured. When the ΔEab value is small, it means that the light resistance is excellent.

[0485]

[0486] After heating the colored film at 230° C. for 60 minutes, the chromaticity change, that is, the ΔEab value was measured. When the ΔEab value is small, it means that the light resistance is excellent.

Abstract

Provided is a colored curable composition capable of producing a color filter that has excellent light resistance, heat resistance, and pattern-forming characteristics, and that exhibits no absorption in the section thereof that is not necessary as a color filter. The colored curable composition contains a phthalocyanine compound that is represented by general formula (1). In general formula (1), X represents a halogen atom, R1 individually represents general formula (2) or general formula (3), and R represents a hydrogen atom or a substituent group. In general formulas (2) and (3), R2 individually represents the substituent groups selected from general formulas (4)-(6), and R3 represents a substituent group.

Description

technical field [0001] The present invention relates to a colored curable composition and a color filter using the colored curable composition. Furthermore, the present invention relates to a liquid crystal display device and a solid-state imaging device using the color filter. In addition, the present invention relates to a method of manufacturing a color filter. Background technique [0002] Conventionally, color filters have been produced by comprising a pigment dispersion composition in which an organic pigment or an inorganic pigment is dispersed, and a multifunctional monomer, a polymerization initiator, an alkali-soluble resin, and other components as necessary. A colored curable composition is formed, and a colored pattern is formed by using the colored curable composition by a photolithography method, an ink-jet method, or the like. [0003] In recent years, color filters tend to be used not only in monitors but also in televisions (TVs) in liquid crystal display ...
