Problems solved by technology

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

[0741] [Preparation method of coloring composition]

[0742] The coloring composition of the present invention is prepared by mixing the above-mentioned respective components and optional optional components.

[0743] In addition, when preparing a coloring composition, each component which comprises a coloring composition may be mix|blended at once, and each component may be melt|dissolved and dispersed in a solvent, and it may mix|blend sequentially. In addition, there are no particular restrictions on the order of loading or working conditions when blending is performed. For example, the composition can be prepared by dissolving and dispersing all the components in a solvent at the same time. If necessary, each component can be prepared into two or more kinds of solutions and dispersions as appropriate, and these solutions can be mixed at the time of use (coating) - Dispersion liquids are mixed to prepare a composition.

[0744] The coloring composition prepared in this ma...

Abstract

Provided are: a colored composition having excellent heat resistance, excellent solvent resistance and an excellent voltage holding ratio; a cured film; a color filter; a method for manufacturing a color filter; a solid-state imaging element; an image display device; and a compound. A colored composition comprising a repeating unit having a triarylmethane structure containing a cation, a coloring agent having a counter anion, and a polymerizable compound.

Description

technical field [0001] The present invention relates to a colored composition, a cured film, a color filter, a method for producing a color filter, a solid-state imaging device, an image display device, and a compound. 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 polyfunctional monomer, a polymerization initiator, an alkali-soluble resin, and other components as necessary. A coloring composition is prepared, and a coloring pattern is formed using the coloring composition by a photolithography method, an inkjet method, or the like. [0003] In recent years, color filters tend to be used not only for monitors but also for televisions (Television, TV) in liquid crystal display elements (liquid crystal displays (Liquid Crystal Display, LCD)). With the tendency to expand such applications, color filters are required to have high colo...
