Title:
CURABLE COMPOSITION, CURED FILM, METHOD FOR FORMING PATTERN, OPTICAL FILTER AND PHOTOSENSOR
Document Type and Number:
WIPO Patent Application WO/2020/066871
Kind Code:
A1
Abstract:
A curable composition according to the present invention is configured such that: the content of a colorant is 30% by mass or more relative to the total solid content of the composition; a photopolymerization initiator contains a photopolymerization initiator A1 that has an absorption coefficient of 1.0 × 103 mL/gcm or more at the wavelength of 365 nm in methanol and a photopolymerization initiator A2 that has an absorption coefficient of 1.0 × 102 mL/gcm or less at the wavelength of 365 nm and an absorption coefficient of 1.0 × 103 mL/gcm or more at the wavelength of 245 nm in methanol; and the ratio of the minimum value A of the absorbance of the composition within the wavelength range of 400-600 nm to the maximum value B of the absorbance of the composition within the wavelength range of 1,000-1,300 nm, namely the ratio A/B is 4.5 or more. The present invention also relates to a cured film, a method for forming a pattern, an optical fiter and a photosensor, to each of which this curable composition is applied.
