Abstract: An optical filter includes an absorption layer containing a near-infrared absorbing dye with an absorption characteristic in dichloromethane satisfying (i-1) to (i-3). (i-1) In an absorption spectrum of a wavelength of 400 to 800 nm, there is a maximum absorption wavelength λmax in 670 to 730 nm. (i-2) Between a maximum absorption coefficient εA of light with a wavelength of 430 to 550 nm and a maximum absorption coefficient εB of light with a wavelength of 670 to 730 nm, the following relational expression: εB/εA≥65 is established. (i-3) In a spectral transmittance curve, the difference between a wavelength λ80 with which the transmittance becomes 80% on a shorter wavelength side than the maximum absorption wavelength with the transmittance at the maximum absorption wavelength λmax set to 10% and the maximum absorption wavelength λmax is 65 nm or less.

Abstract: A fluorinated compound and a fluorinated compound-containing composition which enable formation of a surface layer having high friction resistance and fingerprint marks removability even if the fluorinated compound has a fluorinated organic group having a shorter chain are provided. A coating liquid, an article including the surface layer on its surface, and a method of producing the same are also provided.
A fluorinated compound represented by [(Rf-A-)2N-]a1Q1[-T]b1 (wherein Rf: a fluoroalkyl group or a group having —O— between carbon atoms of a fluoroalkyl group having two or more carbon atoms, A: a divalent organic group having no fluorine atom, Q1: a a1+b1 valent organic group, T: —Si(R)3-c(L)c, R: an alkyl group, L: a hydrolyzable group or a hydroxyl group, a1: an integer of 1 or more, b1: an integer of 2 or more, and c: 2 or 3).
