preparation example Construction

[0128] As the preparation method of titanium black, there is a method of heating and reducing the mixture of titanium dioxide and metallic titanium under a reducing atmosphere (Japanese Patent Application No. 49-5432). The method of reduction in reducing atmosphere (JP-A-57-205322), the method of reducing titanium dioxide or titanium hydroxide at high temperature in the presence of ammonia (JP-A-60-65069, JP-A-61-201610 ), a method of attaching a vanadium compound to titanium dioxide or titanium hydroxide and reducing it at high temperature in the presence of ammonia (JP-A-61-201610), etc., but these methods are not limited.

[0129] Examples of commercially available titanium black include titanium black 10S, 12S, 13R, 13M, and 13M-C manufactured by Mitsubishi Materials.

[0130] As examples of other black pigments, nigrosine, iron oxide-based black pigments, and three-color organic pigments of red, green, and blue can be mixed and used as black pigments.

Abstract

The invention provides a colored curable resin composition having good coating properties even in high speed coating situation. The colored curable resin composition includes (a) a color material, (b) a solvent, (c) at least two kinds of binder resins, (c) a photopolymerization initiator and (e) a surfactant, wherein at least two kinds of the binder resins are resins having 0.0005-0.0050 eq / g of a (meth)acryloyl group and having an acid number of 15-150 mgKOH / g. The invention also provides colored pattern forming method of using the colored curable resin composition, colored pattern, method for manufacturing color filter, color filter and liquid crystal display element.

Description

technical field [0001] The present invention relates to a colored curable resin composition, a colored pattern forming method, a colored pattern, a color filter manufacturing method, a color filter, and a liquid crystal display element. Background technique [0002] A color filter is a colored curable resin composition that contains a binder resin and / or a monomer, a photopolymerization initiator, and other components in a solvent dispersion composition of coloring materials such as organic pigments and inorganic pigments, and uses this The colored curable resin composition is produced by photolithography or the like. [0003] In recent years, in the application of liquid crystal display elements (LCD), there is a trend of expanding the use of color filters not only in monitors but also in televisions (TVs). Also gradually require a high degree of color characteristics. In addition, color filters with high color characteristics are also increasingly required for applicati...
