Abstract
An optical filter containing at least one naphtholactam derivative represented by general formula (I), wherein X is oxygen or sulfur; R1, R2, R3, R4, R5, R6, and Y are each hydrogen, halogen, nitro, cyano, aldehyde, carboxyl, hydroxyl, —NRR′, organosilyl, optionally substituted C1-C30 alkyl, optionally substituted C6-C30 aryl, or optionally substituted C7-C30 arylalkyl; and R and R′ are each hydrogen, optionally substituted C1-C30 alkyl, or optionally substituted C6-C30 aryl.
Claims20
An optical filter comprising at least one naphtholactam derivative represented by general formula (I):
- wherein X represents an oxygen atom or a sulfur atom;
- R1, R2, R3, R4, R5, R6, and Y each independently represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, an aldehyde group, a carboxyl group, a hydroxyl group, —NRR′, an organosilyl group, an optionally substituted alkyl group having 1 to 30 carbon atoms, an optionally substituted aryl group having 6 to 30 carbon atoms, or an optionally substituted arylalkyl group having 7 to 30 carbon atoms;
- the methylene chain of the alkyl group, the methylene chain of the arylalkyl group, and the bond between the aryl group and the naphtholactam structure is optionally interrupted by —O—, —S—, —SO2—, —CO—, —OCO—, or —COO—;
- the methylene chain may be —CH═CH— or —C≡C—;
- and
- R and R′ each independently represent a hydrogen atom, an optionally substituted alkyl group having 1 to 30 carbon atoms, or an optionally substituted aryl group having 6 to 30 carbon atoms.

- and
- an optically functional layer,
- wherein at least one of the substrate and the optically functional layer contains at least one naphtholactam derivative represented by general formula (I):
- wherein X represents an oxygen atom or a sulfur atom;

- the methylene chain of the alkyl group, the methylene chain of the arylalkyl group, and the bond between the aryl group and the naphtholactam structure is optionally interrupted by —O—, —S—, —SO2—, —CO—, —OCO—, or —COO—;
- the methylene chain may be —CH═CH— or —C≡C—;
- and
- R and R′ each independently represent a hydrogen atom, an optionally substituted alkyl group having 1 to 30 carbon atoms, or an optionally substituted aryl group having 6 to 30 carbon atoms.
