Abstract
A coloring composition containing one or more species of compounds represented by Formula (I) or Formula (II) below, wherein each of R1 and R2 represents a hydrogen atom or substituent, each of Ar1 to Ar8 independently represents an optionally substituted aromatic hydrocarbon group or optionally substituted heterocyclic group, and each of L1 and L2 independently represents a divalent linking group which interrupts π electron conjugated system:
Claims20
A coloring composition comprising one or more species of compounds represented by Formula (I) or Formula (II) below:
- in Formula (I), R1 represents a hydrogen atom or substituent, each of Ar1, Ar2, Ar3 and Ar4 independently represents an optionally substituted aromatic hydrocarbon group or optionally substituted heterocyclic group, and L1 represents a divalent linking group which interrupts π electron conjugated system;
- in Formula (II), R2 represents a hydrogen atom or substituent, each of Ar5, Ar6, Ar7 and Ar8 independently represents an optionally substituted aromatic hydrocarbon group or optionally substituted heterocyclic group, and L2 represents a divalent linking group which interrupts π electron conjugated system.
A compound represented by Formula (I) or Formula (II) below:
- in Formula (I), R1 represents a hydrogen atom, substituted or unsubstituted alkyl group, unsaturated hydrocarbon group, substituted or unsubstituted aryl group, substituted or unsubstitued heterocyclic group, halogen atom, cyano group, hydroxy group, substituted or unsubstituted carbamoyl group, substituted or unsubstituted sulfamoyl group, nitro group, substituted or unsubstituted alkoxy group, substituted or unsubstituted aryloxy group, substituted or unsubstituted acyl group, acyloxy group, alkoxyacyl group, acylamino group, substituted or unsubstituted sulfonyl group, amino group, or substituted amino group, each of Ar1, Ar2, Ar3 and Ar4 independently represents an optionally substituted aromatic hydrocarbon group or optionally substituted heterocyclic group, and L1 represents a divalent linking group which interrupts π electron conjugated system;
- in Formula (II), R2 represents a hydrogen atom, substituted or unsubstituted alkyl group, unsaturated hydrocarbon group, substituted or unsubstituted amyl group, substituted or unsubstituted heterocyclic group, halogen atom, cyano group, hydroxy group, substituted or unsubstituted carbamoyl group, substituted or unsubstituted sulfamoyl group, nitro group, substituted or unsubstituted alkoxy group, substituted or unsubstituted aryloxy group, substituted or unsubstituted acyl group, acyloxy group, alkoxyacyl group, acylamino group, substituted or unsubstituted sulfonyl group, amino group, or substituted amino group, each of Ar5, Ar6, Ar7 and Ar8 independently represents an optionally substituted aromatic hydrocarbon group or optionally substituted heterocyclic group, and L2 represents a divalent linking group which interrupts electron conjugated system.
