BLACK RESIN COMPOSITION, NEAR INFRARED RAY-TRANSMITTING LIGHT-BLOCKING MEMBRANE, DECORATIVE SUBSTRATE, DECORATIVE FILM AND COLORED PARTITION WALL FOR ORGANIC EL DISPLAY

摘要

The present invention addresses the problem of providing a black resin composition that exhibits an achromatic reflection color tone, that has high visible light-shielding performance and near infrared ray-transmissivity, and that produces little transmitted scattered light. The present invention provides a black resin composition containing (A) a resin, (B) a coloring material, and (C) an organic solvent, the black resin composition being characterized by including a red pigment and a blue pigment as the coloring material (B), and characterized in that the content of the red pigment with respect to the total amount of the coloring material (B) is 20-80 wt%, and that the crystallite size of the red pigment is 5-25 nm, where the crystallite size is calculated from the half width obtained from the main peak of an x-ray diffraction spectrum of a colored membrane made of a cured product of the black resin composition, the spectrum being obtained when CuKα ray is used as the source of X ray.
