Abstract

PURPOSE: The titled photosensitive composition with reverse photochromic characteristics having high contrast, resolution and photosensitivity, and prolonged color development and extinction cycle life, which comprises a specified spiran deriv.
CONSTITUTION: A spiran deriv. of the formula (wherein R1 is 12W30C alkyl; R2 is H, 1W5C alkyl 1W5C alkoxy, 2W5C alkoxycarbonyl, halogen or nitro) prepd. by replacing 6',8'-dinitroindolinobenzopyrrylyl-spiran at the N position with an alkyl group having a large number of carbon atoms. Although usually, said compd. having visible ray absorption at about 500W600nm, is colored in magenta, the color is extinguished upon irradiation with a visifle or UV ray, while it is developed again upon heating at a temp. ≥ about 60°C; the so called reverse photochromism.
