Problems solved by technology

[0004] However, in the existing pigment dispersion system, it is easy to cause problems such as scattering due to coarse pigment particles, viscosity increase due to poor dispersion stability, and it is often difficult to further improve contrast and brightness.

[0179] [Manufacturing Method of Colored Curable Composition]

[0180] The colored curable composition of the present invention is prepared by mixing the above-mentioned components and optional components as needed.

[0181] In addition, at the time of preparation of the curable colored composition, each component constituting the curable colored composition may be blended at one time, or may be blended sequentially after dissolving and dispersing each component in a solvent. In addition, there are no special restrictions on the input sequence or working conditions at the time of deployment. For example, the composition can be prepared by dissolving and dispersing all the components in a solvent at the same time, or if necessary, each component can be prepared in advance as two or more kinds of appropriate solutions and dispersions, and these solutions and dispersions can be mixed at the time of use (coating) Liquids are mixed to prepare compositions.

Abstract

A colored curable composition having high color purity and superior transmissivity is provided. The colored curable composition is soluble in an organic solvent, with main absorption in the range of 680-800 nm in a chloroform solvent, and contains a phthalocyanine compound having a substructure comprising at least one of a chlorine atom and a bromine atom, as well as one or more substituents represented by general formula (1), on the same benzene nucleus. In general formula (1), X1 represents an oxygen atom, a sulfur atom, an SO2 group, or an NH group; and R1 represents an alkyl group or an aryl group.

Description

technical field [0001] The present invention relates to a colored curable composition and a color filter using the colored curable composition. It also relates to a liquid crystal display device and a solid-state imaging device using the color filter. It also relates to a method for manufacturing a color filter. Background technique [0002] Conventionally, color filters are manufactured by containing a pigment dispersion composition obtained by dispersing an organic pigment or an inorganic pigment, a multifunctional monomer, a polymerization initiator, an alkali-soluble resin, and other components as necessary , to make a colored curable composition, and use this colored curable composition to form a colored pattern by photolithography, inkjet method, or the like. [0003] In recent years, the use of color filters tends to expand not only to monitors in liquid crystal display (LCD) applications but also to televisions (TVs). Accompanying the tendency to expand such appli...
