Problems solved by technology

[0011] However, when a pixel containing the above-mentioned dye was produced and the chromaticity was measured, after high-temperature drying at 230°C at the time of pixel formation, the luminance decreased compared to before high-temperature drying.
Dye-based colorants have the problem of being unable to obtain sufficient high brightness due to heat treatment because they are inferior in heat resistance compared to conventionally used pigments.
This suggests that if the decrease in brightness due to heat treatment can be suppressed, there is room for further improvement in brightness

Abstract

A coloring composition for a color filter is provided to prevent the degradation of brightness in a thermal process over 180[deg.]C especially 230[deg.]C and to produce a filter segment with high brightness. A coloring composition for a color filter contains a coloring agent [A], a resin [B], and a monomer [C].The coloring agent [A] includes a dye. The monomer [C] contains a monomer [C1] having an isocyanurate structure indicated as the following chemical formula (1). In the following chemical formula (1), R1, R2 and R3 are respectively a radical indicated as the following chemical formula (2)- (6) and at least one of each radical is a radical indicated as the following chemical formula (2)- (4). In the chemical formula (2)- (6), R4, R5 and R6 are respectively H or any one of CH3-, N is the fixed number of 0-10, ms are respectively the fixed number of 1-20, and I is the fixed number of 1-5.

Description

technical field [0001] This invention relates to the coloring composition for color filters used for manufacture of the color filter contained in a color liquid crystal display device, a color imaging element, etc., and the color filter provided with the filter segment and / or black matrix formed using it. Background technique [0002] A liquid crystal display device has a structure in which a liquid crystal substance and a plurality of pixels are sandwiched between two polarizing plates. In a liquid crystal display device, a voltage is applied to each pixel to change the alignment state of the liquid crystal material and change the degree of polarization of the light passing through the first polarizer, thereby controlling the transmitted light through the second polarizer to display image. [0003] The liquid crystal display device can perform color display by disposing a color filter between these two polarizing plates, and is used in television receivers, personal comput...
