NEW MATERIAL:A compound expressed by formula I [X<1>, X<2>, Y<1> and Y<2> represent alkyl, alkoxyalkyl, cycloalkyl or aryl, or X<1> and X<2> as well as Y<1> and Y<2> may be linked with each other to form a ring; Z represents optionally substituted alkylene which may be linked through other group or atom, or (substituted) arylene; R<1>-R<8> represent H, halogen atom, alkyl, alkoxy (carbonyl), alkoxysulfonyl or alkylsulfonyl]. EXAMPLE:A compound expressed by formula II. USE:A coloring matter for a photosensitive material having photochromic property. PREPARATION:For example, a 2,3,3-trimethylinodolenine derivative expressed by formulae III and IV is reacted with a dihalide expressed by the formula A-Z-A (A represents halogen atom) and further reacted with a 1-nitroso-2- naphthol derivative expressed by formulae V and VI. |
