<p>The invention provides a near infrared absorbing material by which light fastness and other properties are obtainable at the same time. The near infrared absorbing material includes (1) at least one compound selected from a singlet oxygen trapping agent, a radical trapping agent and / or an antioxidant, and (2) at least one compound having a spectroscopic absorption maximum wavelength of 700 nm or longer in a wavelength region from 400 to 1600 nm in solution. In Formula (I-1) and (I-2) of the compound (1), R11 represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group bonded to a carbon atom, or a hydrolyzable protective group; R12 to R16 each independently represent a hydrogen atom or a substituent; R21 represents a hydrogen atom, an aliphatic group, an acyl group, a sulfonyl group, a sulfinyl group, an oxyradical group or a hydroxy group; Q represents a group of non-metallic atoms necessary for forming a 5-, 6- or 7-membered ring; and R22 to R25 each independently represent a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group bonded to a carbon atom.</p> |
