Patent ID: 7875215

Claim:
A near-infrared-absorbing filter provided with a near-infrared-absorbing material comprising at least one first compound selected from the group consisting of a singlet oxygen scavenger, a radical trapping agent and an antioxidant, the at least one first compound being a combination of a compound represented by the following formula (I-1) and a compound represented by the following formula (I-2), and at least one second compound represented by the following formula (II-2): wherein R 11 represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group bound via a carbon atom, or a hydrolysable protective group; R 12 to R 16 each independently represents a hydrogen atom or a substituent group; R 11 and R 12 , R 12 and R 13 , R 13 and R 14 , R 14 and R 15 , R 15 and R 16 , and R 16 and R 11 may be bound to each other to form a ring; R 21 represents a hydrogen atom, an aliphatic group, an acyl group, an alkyl or aryl sulfonyl group, an alkyl or aryl sulfinyl group, an oxy radical group or a hydroxyl group; Q represents a nonmetallic atomic group necessary for forming a 5-, 6- or 7-membered ring; R 22 to R 25 each independently represents a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group bound via a carbon atom; and R 21 and R 22 , R 22 and R 23 , R 24 and R 25 , and R 21 and R 24 may be bound to each other to form a ring; wherein R 211 , R 212 , R 221 and R 222 each independently represents a hydrogen atom, an aliphatic group, an aromatic, group, or a heterocyclic group bound via a carbon atom; R 213 to R 216 and R 223 to R 226 each represents a hydrogen atom or a substituent group; and R 213 and R 214 , R 214 and R 211 , R 211 and R 212 , R 212 and R 215 , R 215 and R 216 , R 223 and R 224 , R 224 and R 221 , R 221 and R 222 , R 222 and R 225 , and R 225 and R 226 may be bound to each other to form a ring, wherein the total amount of the first compound being a combination of the compound represented by formula (I-1) and the compound represented by formula (I-2) is from 0.1 to 2 moles per mole of the second compound represented by formula (II-2), and the content of the second compound represented by formula (II-2) is from 10 −4 % by weight to 3% by weight with respect to the total solid content of the near-infrared-absorbing material.
