Document Type and Number:
Japanese Patent JP6636434
Kind Code:
B2
Abstract:
Provided are a composition in which particles including a pyrrolopyrrole pigment have excellent dispersibility, a composition production method, a curable composition, a cured film using a curable composition, a near-infrared cut-off filter, a solid-state image-acquisition device, an infrared sensor, and a camera module. A composition that contains particles including a pigment represented by formula (1) and in which the particles have an average secondary-particle diameter of 500 nm or less is provided. Each of R1 a and R1b independently represents an alkyl group, an aryl group, or a heteroaryl group; each of R2 and R3 independently represents a hydrogen atom or a substituent group; R2 and R3 may be bonded to each other to form a ring; R4 represents a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, -BR4AR4B, or a metal atom; R4 may be bonded to at least one selected from R1a, R1b, and R3 by a covalent bond or a coordinate bond; and each of R4A and R4B independently represents a hydrogen atom or a substituent group.
