Abstract:
There is provided a near-infrared cut filter which has a visible light transmitting property and a near-infrared shielding property both at high levels by that its transmission spectrum has a steep inclination in the vicinity of the boundary between the visible light and the near-infrared, and which can also be sufficiently reduced in size and thickness. The near-infrared cut filter has a near-infrared absorbing layer which contains a near-infrared absorbing dye containing at least one dye in which a condensed ring structure containing at least a benzene ring and a ring having nitrogen atom is bonded to both sides of a squarylium skeleton and which have a carboxylic acid amide structure at a second position of the benzene ring (where the carboxylic acid has a substituent having 5 to 25 having one or more branches), and a transparent resin with a refractive index of 1.45 or more.

Claim (Index 13):
A near-infrared cut  \u2212 filter comprising:\n a near-infrared cut filter comprising a near-infrared absorbing layer, wherein: the near-infrared absorbing layer comprises a near-infrared absorbing dye and a transparent resin; and the near-infrared absorbing dye comprises at least one dye according to formula (A1): where:\n each X is independently a bivaalent organic group according to formula (1) or formula (2):\n \u2014(CH 2 ) n1 \u2014\u2003\u2003(1) \n \n where n1 is 2 or 3:\n \u2014(CH 2 ) n2 \u2014O\u2014(CH 2 ) n3 \u2014\u2003\u2003(2) \n where each n2 and n3 is independently an integer of 0 to 2, and n2+n3 is 1 or 2:\n one or more hydrogen atoms in formula (1) and formula (2) may be substituted with an alkyl group or alkoxy group having 1 to 12 atoms; \n each R 1  is independently a saturated or unsaturated hydrocarbon group having 1 to 12 carbon atoms which may include a saturated ring structure and may have a branch, a saturated cyclic hydrocarbon group having 3 to 12 carbon atoms, an aryl group having 6 to 12 carbon atoms, or an alanyl group having 7 to 13 carbon atoms; \n each R 2  and R 3  is independently a hydrogen atom, a halogen atom, or an alkyl group or alkoxy group having 1 to 10 carbon atoms; and \n each R 4  is independently a hydrocarbon group having 5 to 25 carbon atoms, in which one or more hydrogen atoms may be substituted by a halogen atom, a hydroxyl group, a carboxy group, a sulfa group, or a cyano group, and in which the hydrocarbon group may contain an unsaturated bond, an oxygen atom, or a saturated or unsaturated ring structure between carbon atoms.
