Beschreibung
Zusammenfassung:NEW MATERIAL:A compound expressed by formula I [X , X , Y and Y are (alkoxy)alkyl, cycloalkyl or aryl; X and X and Y and Y together may link to form a ring; Z is (substituted)alkylene or (substituted)arylene; R -R are H, halogen, alkyl, alkoxy(carbonyl), alkoxysulfonyl or alkylsulfonyl]. EXAMPLE:A compound expressed by formula II. USE:A photochromic photosensitive material, having excellent heat resistance, high coloring density as well as improved fastness, capable of coloring by irradiation with ultraviolet rays and then returning to the original color by irradiation with visible rays or heating to >=50 deg.C. PREPARATION:2,3,3-Trimethylindolenine derivatives expressed by formulas III and IV are reacted with a dihalide expressed by the formula A-Z-A (A is halogen) and the resultant products are then reacted with 9-nitroso-10- hydroxynaphthalene derivatives expressed by formulas V and VI.
