Problems solved by technology

However, when the content of the coloring material in the colored resin composition is increased, there is a problem that in order to exhibit excellent optical characteristics, the pigment must be micronized, especially when the high-concentration pigment dispersion composition is produced, the viscosity increases, or The storage stability of the pigment dispersion composition such as gelation during storage deteriorates, thereby also reducing optical properties such as brightness and contrast
[0005] Japanese Patent Laid-Open No. 2013-61619 relates to a cyan colorant composition for color filters and a color filter substrate using the same, and discloses a cyan colorant composition for color filters containing at least a colorant and a binder A cyan colorant composition for a color filter comprising a resin, a polymer dispersant, and a solvent, wherein the colorant contains a pigment and a rhodamine-based dye, and the rhodamine-based dye is in the form of particles in the cyan colorant composition. The state exists, but the actual situation is that the dispersion stability is not excellent, and the contrast is slightly difficult to apply to high-quality color filters

Synthetic example 1

[0130] Synthesis Example 1: Triazine Compound 1

[0131] Add 18.4 parts by weight of 2-chloro-4,6-diamino-1,3,5-triazine and 21 parts by weight of 3-(2-ethylhexyloxy)propylamine to 100 parts by weight of water. Reacted for 1 hour. The obtained reactant was reacted at 85° C. for 5 hours. The residue obtained by leaching the obtained reactant was washed with water, and then left to stand overnight in a thermostat at 100° C. to dry, thereby obtaining a compound of the following chemical formula 2.

Abstract

The present invention relates to a colored photosensitive resin composition, specifically, to a colored photosensitive resin composition, a color filter and an image display device manufactured using the colored photosensitive resin composition, the colored photosensitive resin composition comprising: rhodan in a particle state Colorants for Ming dyes and pigments; and Dispersants containing triazine compounds.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter manufactured using the same, and an image display device. Background technique [0002] Color filters are widely used in various display devices such as imaging elements and liquid crystal display devices (LCD), and the range of applications thereof is rapidly expanding. The above-mentioned color filter consists of a coloring pattern of three colors of red (Red), green (Green) and blue (Blue), or of three colors of yellow (Yellow), magenta (Magenta) and cyan (Cyan) composition of coloring patterns. [0003] The color filters widely used in the above-mentioned display devices are usually produced by changing the coloring photosensitivity of the pigment dispersion composition containing the color corresponding to each pattern by spin coating or slit coating on the substrate on which the black matrix pattern is formed. After the resin composition is uniformly app...
