Title:
LIGHT-SENSITIVE COLORING COMPOSITION, CURED FILM, COLOR FILTER, SOLID-STATE IMAGING ELEMENT, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/173570
Kind Code:
A1
Abstract:
Provided are: a light-sensitive coloring composition having excellent photolithographic properties and with which it is possible to suppress the incidence of color mixture between adjacent pixels having other color phases; a cured film using the light-sensitive coloring composition; a color filter; a solid-state imaging element; and an image display device. The light-sensitive coloring composition includes a magenta pigment having an average primary particle diameter of 50 nm or less, a polymerizable compound, a photopolymerization initiator, and a UV absorbent. The magenta pigment has a maximum absorption wavelength in the range of 500-600 nm, and when the absorbance of the maximum absorption wavelength is defined as 1, the wavelength at which absorbance is 0.5 is 450 nm or more on the short wavelength side of the maximum absorption wavelength, and 650 nm on the long wavelength side of the maximum absorption wavelength.
