First claim

What is claimed is:

1 . A photochromic compound represented by the following General Formula 1:

(in General Formula 1, R 100 to R 111 , and X 1 and X 2 each independently represent a hydrogen atom or a substituent, and two or more substituents may be bonded to form a ring structure).

2 . A photochromic compound represented by the following General Formula 2:

(in General Formula 2, R 200 to R 211 , and X 3 and X 4 each independently represent a hydrogen atom or a substituent, and two or more substituents may be bonded to form a ring structure).

3 . A photochromic compound represented by the following General Formula 3:

(in General Formula 3, R 300 to R 311 , and X 5 and X 6 each independently represent a hydrogen atom or a substituent, and two or more substituents may be bonded to form a ring structure).

4 . The photochromic compound according to claim 1 ,
wherein the substituent is a substituent R m selected from the group consisting of a hydroxy group, linear or branched alkyl groups having 1 to 18 carbon atoms, monocyclic or multicyclic cycloaliphatic alkyl groups having 5 to 18 carbon atoms, linear or branched alkoxy groups having 1 to 24 constituent atoms, non-aromatic cyclic substituents having 1 to 24 constituent atoms, linear or branched perfluoroalkyl groups having 1 to 18 carbon atoms, linear or branched perfluoroalkoxy group, linear or branched alkylsulfide groups having 1 to 24 constituent atoms, an aryl group, aryloxy group, arylsulfide group, heteroaryl group, amino group, monoalkylamino group, dialkylamino group, monoarylamino group, diarylamino group, cyclic amino group, ethynyl group, mercapto group, silyl group, sulfonic acid group, alkyl sulfonyl group, formyl group, carboxy group, and cyano group and halogen atoms; or a substituent in which R m is additionally substituted with one or more of the same or different R m 's.

5 . A photochromic composition comprising the photochromic compound according to claim 1 .

6 . A photochromic composition comprising the photochromic compound according to claim 2 .

7 . A photochromic composition comprising the photochromic compound according to claim 3 .

8 . The photochromic composition according to claim 5 ,
wherein the substituent is a substituent R m selected from the group consisting of a hydroxy group, linear or branched alkyl groups having 1 to 18 carbon atoms, monocyclic or multicyclic cycloaliphatic alkyl groups having 5 to 18 carbon atoms, linear or branched alkoxy groups having 1 to 24 constituent atoms, non-aromatic cyclic substituents having 1 to 24 constituent atoms, linear or branched perfluoroalkyl groups having 1 to 18 carbon atoms, linear or branched perfluoroalkoxy group, linear or branched alkylsulfide groups having 1 to 24 constituent atoms, an aryl group, aryloxy group, arylsulfide group, heteroaryl group, amino group, monoalkylamino group, dialkylamino group, monoarylamino group, diarylamino group, cyclic amino group, ethynyl group, mercapto group, silyl group, sulfonic acid group, alkylsulfonyl group, formyl group, carboxy group, and cyano group and halogen atoms; or a substituent in which R m is additionally substituted with one or more of the same or different R m 's.

9 . The photochromic composition according to claim 5 , further comprising a polymerizable compound.

10 . The photochromic composition according to claim 6 , further comprising a polymerizable compound.

11 . The photochromic composition according to claim 7 , further comprising a polymerizable compound.

12 . A photochromic article comprising a cured product obtained by curing the photochromic composition according to claim 9 .

13 . A photochromic article comprising a cured product obtained by curing the photochromic composition according to claim 10 .

14 . A photochromic article comprising a cured product obtained by curing the photochromic composition according to claim 11 .

15 . The photochromic article according to claim 12 , comprising a substrate and a photochromic layer which is the cured product.

16 . The photochromic article according to claim 12 , which is a spectacle lens.

17 . The photochromic article according to claim 12 , which is a goggle lens.

18 . The photochromic article according to claim 12 , which is a visor part of a sun visor.

19 . The photochromic article according to claim 12 , which is a shield member of a helmet.

20 . Eyeglasses comprising the spectacle lens according to claim 16 .
