Abstract:
1. An optical recording material comprising at least one compound represented by general formula (I): wherein R in the general formula (II), the bond between G and T is a double bond, a conjugated double bond, or a triple bond; G represents a carbon atom; T represents a carbon atom, an oxygen atom, or a nitrogen atom; w represents a number of 0 to 4; x, y, and z each represent 0 or 1 provided that, when T is oxygen, y=z=0, and when T is nitrogen, y+z=0 or 1; R 01 , R 02 , R 03 , and R 04 each independently represent a hydrogen atom, a hydroxyl group, a cyano group, a nitro group, a halogen atom, or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms, the methylene moiety of which may be substituted with —O— or —CO—; and R 01 and R 04 may be taken together to form a ring structure; in the general formula (II′), the bond between G′ and T′ is a double bond or a conjugated double bond; G′ represents a carbon atom; T′ represents a carbon atom or a nitrogen atom; w′ represents a number of 0 to 4; R 01′ represents a hydrogen atom, a hydroxyl group, a cyano group, a nitro group, a halogen atom, or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms, of which the methylene moiety may be substituted with —O— or —CO—; and the ring containing G′ and T′ is a 5-membered ring that may contain a hetero atom, a 6-membered ring that may contain a hetero atom, a naphthalene ring, a quinoline ring, an isoquinoline ring, an anthracene ring, or an anthraquinone ring and may be substituted with a halogen atom, a nitro group, a cyano group, an alkyl group or an alkoxy group, wherein R a , R b , R c , R d , R e , R f , R g , R h , and R i each independently represent a hydrogen atom or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms, the methylene moiety of which may be substituted with —O— or —CO—; Q represents a single bond or a substituted or unsubstituted alkylene group having 1 to 10 carbon atoms, of which the methylene group may be substituted with —O—, —S—, —CO—, —COO—, —OCO—, —SO 2 —, —NH—, —CONH—, —NHCO—, —N═CH—, or —CH═CH—; and M is as defined above.
