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); X1, X2, Y1, and Y2 each represents an alkyl group, or X1 and X2, or Y' and Y2, 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; R1, R2, R3, R4, R5, and R6 each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group, an alkoxysulfonyl group or an alkylsulfonyl group.
由通式(I)代表的螺恶嗪化合物,具有优异的耐热性和光致变色性能,在基板上提供的树脂中含有该化合物的感光材料,以及将光致变色材料形成薄膜或其它形状的工艺,该工艺包括将该化合物直接加入高分子材料中,其中A和A'相同并代表基团(II)、(III)或(IV);X1、X2、Y1 和 Y2 各代表一个烷基,或 X1 和 X2 或 Y' 和 Y2 可相互结合形成一个环己烷环; Z 代表选自基团(V)和(VI)(这些基团可选择具有取代基)、可选择被氧原子打断的直链或支链亚烷基或可选择取代的芳烯基;R1、R2、R3、R4、R5 和 R6 各自代表氢原子、卤素原子、烷基、烷氧基、烷氧羰基、烷氧磺酰基或烷磺酰基。
