SPIROOXAZINE COMPOUNDS, PHOTOSENSITIVE MATERIALS USING THEM, AND PROCESS FOR FORMING THEM.

摘要

Spirooxazine compounds represented by general formula (I), excellent in heat resistance and photochromic properties, photosensitive materials containing the compounds in a resin provided on a base plate, and a process for forming photochromic materials into film or other shapes comprising directly incorporating the compounds in a high-molecular material, wherein A and A' are the same and represent groups (II), (III), or (IV); X<1>, X<2>, Y<1>, and Y<2> each represents an alkyl group, or X<1> and X<2>, or Y<1> and Y<2>, may be bound to each other to form a cyclohexane ring; Z represents a group selected from among groups (V) and (VI) (these groups optionally having substituents), a straight-chain or branched alkylene group optionally interrupted by an oxygen atom, or an optionally substituted arylene group; R<1>, R<2>, R<3>, R<4>, R<5>, and R<6> each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group, an alkoxysulfonyl group or an alkylsulfonyl group.
