Document Type and Number:
WIPO Patent Application WO/2023/054143
Kind Code:
A1
Abstract:
A curable composition comprising an infrared absorption reagent, a polymerizable monomer, and photoinitiators, wherein the photoinitiators include a photoinitiator IA having an absorption coefficient of 1.0×103 mL/g·cm or more with respect to a wavelength of 365 nm in methanol, and a photoinitiator IB having, in methanol, an absorption coefficient of less than 1.0×103 mL/g·cm with respect to a wavelength of 365 nm and having an absorption coefficient of 1.0×103mL/g·cm or more with respect to a wavelength of 254 nm, and A1/A2, which is the ratio of the maximum value A1 of the absorbance of the curable composition in a wavelength range of 700-2000 nm with respect to the maximum value A2 of the absorbance of the curable composition in a wavelength range of 400-600 nm, is 4.5 or more. A cured film, a pattern forming method, a near infrared cut-off filter, a solid image pickup element, an image display apparatus, and an infrared sensor, in all of which said curable composition is used.
