Title:
CURABLE COMPOSITION, CURED FILM, OPTICAL FILTER, SOLID-STATE IMAGING ELEMENT, IMAGE DISPLAY DEVICE, INFRARED SENSOR, DISPERSION AID, LIQUID DISPERSION, AND PRODUCTION METHOD FOR LIQUID DISPERSION
Document Type and Number:
WIPO Patent Application WO/2018/230387
Kind Code:
A1
Abstract:
Provided are: a curable composition which has excellent moisture resistance, and with which a cured film can be produced in which the occurrence of aggregate derived from a compound having a pigment backbone is inhibited; a cured film; an optical filter; a solid-state imaging element; an image display device; an infrared sensor; a dispersion aid; a liquid dispersion; and a production method for the liquid dispersion. This curable composition has a structure in which at least one functional group selected from acid groups having a pKa of 3 or lower and a ClogP value of -1.1 or higher, anionic groups resulting from dissociation of one or more hydrogen atoms from the acid groups, and salts of the acid groups, is bonded to a π conjugated structure of a pigment backbone having the π conjugated structure, and contains a compound A having a maximum absorption wavelength within the wavelength range of 650-1200 nm, a curable compound, and a solvent.
