Abstract

PURPOSE:To reduce the cost while facilitating the handling by compounding an indolinospiropyran compound into a nitrocellulose resin. CONSTITUTION:One or more of indolinospiropyran compounds as photochromic material are compounded into a nitrocellulose resin to form an illumination intensity indicating material. When dissolved in the film of the nitrocellulose resin, the spiropyran acts as color developing seed in time and stabilized. Nitrocelluloe resins of various degrees of polymerization for use in film, celluloid, lacquer or the like are used.
