LIGHT-BLOCKING PIGMENT COMPOSITION AND LIGHT-BLOCKING MEMBER FOR DISPLAY

摘要

Provided is a light-blocking pigment composition which has high insulation properties and a low dielectric constant and which can satisfy high optical density, and a light-blocking member for display, which contains the light-blocking pigment composition. When a pigment composition containing a benzimidazolone dioxazine-based pigment, a benzimidazolone-based pigment, and a carbazole dioxazine-based pigment in a specific ratio is used for a light-blocking member for display, since the light-blocking member has high insulation properties, a low dielectric constant, and high optical density, it is possible to provide a display having high light-blocking properties.

主权项

1. A light-blocking pigment composition, comprising:
from 5% by weight to 80% by weight of a benzimidazolone dioxazine-based pigment represented by General Formula (1) below; from 20% by weight to 50% by weight of a benzimidazolone-based pigment having chemical structures of General Formula (2) and General Formula (3) below; and from 5% by weight to 80% by weight of a carbazole dioxazine-based pigment having at least one chemical structure of General Formulae (4) to (6) below: wherein each of R1 to R4 represents a hydrogen atom or a monovalent hydrocarbon group which may have a substituent, and X1 represents a hydrogen atom or a halogen atom; wherein each of R5 to R7 represents a hydrogen atom, a halogen atom, or a monovalent hydrocarbon group which may have a substituent; and wherein X2 represents a hydrogen atom or a halogen atom, and R8 represents a hydrogen atom or a monovalent hydrocarbon group which may have a substituent.
