PHOTOCHROMIC PHOTOSENSITIVE MATERIAL

摘要

PURPOSE:To prevent deterioration by long-time irradiation with light by incorporating a specified bisphenolic compd. and a specified nickel complex as additives into a photochromic spiroxazine compd. CONSTITUTION:A bisphenolic compd. represented by formula I (where each of X<1> and X<4> is alkyl and each of X<2> and X<3> is H or alkyl) and a nickel complex represented by formula II (where each of X<5>-X<7> is 1-10C alkyl) are incorporated into a photochromic photosensitive compsn. contg. a spiroxazine compd. and a high molecular material. Deterioration by long-time irradiation with light can be prevented.
