wherein the photochromic compound is represented by the following formula (1):, the compound being a chromene compound having an indenonaphthopyran moiety represented by the formula (1),
wherein:
R1 and R2 each independently represent the oligomer chain group A, the alkenyl group having 10 to 30 carbon atoms, a group having an alkenyl group having 10 to 30 carbon atoms at the terminal thereof, a hydroxy group, an alkyl group, a haloalkyl group, a cycloalkyl group optionally having a substituent, an alkoxy group, an amino group, a substituted amino group, a heterocyclic group optionally having a substituent, a cyano group, a halogen atom, an alkylthio group, an arylthio group optionally having a substituent, a nitro group, a formyl group, a hydroxycarbonyl group, an alkylcarbonyl group, an alkoxycarbonyl group, an aralkyl group optionally having a substituent, an aralkoxy group optionally having a substituent, an aryloxy group optionally having a substituent, an aryl group optionally having a substituent, a heteroaryl group optionally having a substituent, a thiol group, an alkoxyalkylthio group, a haloalkylthio group, or a cycloalkylthio group optionally having a substituent;
a represents an integer of 0 to 4, and b represents an integer of 0 to 4,
when a is 2 to 4, plural R1‘s may be the same or different,
when b is 2 to 4, plural R2's may be the same or different,
when a is 2 to 4 and when the compound has neighboring R1's, the neighboring R1's may form together and along with the carbon atoms bonding to these R1's, a ring optionally containing an oxygen atom, a carbon atom, a sulfur atom, or a nitrogen atom, and further the ring may have a substituent;
when b is 2 to 4 and when the compound has neighboring R2's, the neighboring R2's may form together and along with the carbon atoms bonding to these R2's, a ring optionally containing an oxygen atom, a carbon atom, a sulfur atom, or a nitrogen atom, and further the ring may have a substituent;
R3 and R4 each independently represent an aryl group optionally having a substituent, or a heteroaryl group optionally having a substituent;
R5 and R6 each independently represent the alkenyl group having 10 to 30 carbon atoms, the oligomer chain group A, a group having an alkenyl group having 10 to 30 carbon atoms at the terminal thereof, a hydrogen atom, a hydroxy group, an alkyl group, a haloalkyl group, a cycloalkyl group, an alkoxy group, an alkoxyalkyl group, a formyl group, a hydroxycarbonyl group, an alkylcarbonyl group, an alkoxycarbonyl group, a halogen atom, an aralkyl group optionally having a substituent, an aralkoxy group optionally having a substituent, an aryloxy group optionally having a substituent, an aryl group optionally having a substituent, or a heterocyclic group optionally having a substituent;
R5 and R6 may together form, along with the 13-positioned carbon atom in the indenonaphthopyran moiety to which they bond, an aliphatic ring having 3 to 20 ring carbon atoms, a condensed polycyclic ring formed by condensation of the aliphatic ring with an aromatic ring or an aromatic hetero ring, a hetero ring having 3 to 20 ring atoms, or a condensed polycyclic ring formed by condensation of the hetero ring with an aromatic ring or an aromatic hetero ring, and these rings may have a substituent, or also they may form, along with the 13-positioned carbon atom in the indenonaphthopyran moiety to which they bond, an aliphatic hydrocarbon ring having 3 to 20 ring carbon atoms, a condensed polycyclic ring formed by condensation of the aliphatic hydrocarbon ring with an aromatic ring or an aromatic hetero ring, a hetero ring having 3 to 20 ring atoms, or a condensed polycyclic ring formed by condensation of the hetero ring with an aromatic hydrocarbon ring or an aromatic hetero ring;
the substituent of the group optionally having a substituent may be a group having an alkenyl group having 10 to 30 carbon atoms at the terminal thereof, an alkenyl group having 10 to 30 carbon atoms, or the oligomer chain group A,
or,
the substituent of the group optionally having a substituent may be the alkenyl group having 10 to 30 carbon atoms or a group having an alkenyl group having 10 to 30 carbon atoms at the terminal thereof in such a manner that the number of the alkenyl group having 10 to 30 carbon atoms can be 1 to 12 per one oligomer chain group A contained in one molecule.
