Title:
COLORED RESIN COMPOSITION, OPTICAL FILTER AND SOLID-STATE IMAGING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/243353
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a colored resin composition which is capable of forming an optical filter that has excellent heat resistance. The preset invention provides a colored resin composition which contains a coloring agent, an alkali-soluble resin and a solvent. The coloring agent contains at least one compound that is selected from the group consisting of compounds represented by formula (I) and formula (II). The maximum absorption wavelength within the wavelength range of 380 nm to 1,400 nm is 799 nm or less. (In formula (I), M1 represents a divalent metal atom; each of R1 to R8 represents a hydrocarbon group having 1 to 20 carbon atoms, or the like; R17 represents a hydrocarbon group having 1 to 20 carbon atoms, or the like; and each of A1 to A8 represents an aryl group having 6 to 20 carbon atoms, or the like.) (In formula (II), M2 represents a divalent metal atom; each of R9 to R16 represents a saturated hydrocarbon group having 1 to 10 carbon atoms; and each of A9 to A16 represents an aryl group having 6 to 20 carbon atoms, or the like.)
