BLACK RESIN COMPOSITION FOR LIGHT BLOCKING FILMS, SUBSTRATE WITH LIGHT BLOCKING FILM OBTAINED BY CURING COMPOSITION, COLOR FILTER HAVING SUBSTRATE WITH LIGHT BLOCKING FILM, AND TOUCH PANEL

摘要

PROBLEM TO BE SOLVED: To provide a black resin composition for light blocking films which is used to obtain a light blocking film that offers reduced reflectance, and to provide a substrate with the light blocking film formed thereon.SOLUTION: A black resin composition for light blocking films contains essential ingredients of (A) a light- or heat-curable resin and/or light- or heat-curable monomer, (B) a black light blocking particle-containing dispersion liquid comprising black light-blocking particles dispersed in a dispersion medium, and (C) a transparent particle-containing dispersion liquid comprising transparent particles dispersed in a dispersion medium. The black resin composition is characterized in that: a ratio D/Dof an average secondary particle diameter Dof the transparent particles in the ingredient (C) to an average secondary particle diameter Dof the black light-blocking particles in the ingredient (B) is in a range of 0.2 to 1.0; a ratio m/mof a mass mof the transparent particles in the ingredient (C) to a mass mof the black light-blocking particles in the ingredient (B) is in a range of 0.015 to 0.20; and the transparent particles have a refractive index that is no greater than that of a hardened product of the ingredient (A).SELECTED DRAWING: None
