PURPOSE:To prepare an organic optical memory material which is excellent in the response to light and heat, reproducibility, and storage stability of written recording, by incorporating a particular diphenylanthracene compd. CONSTITUTION:An org. optical memory material comprising an endoperoxide of a compd. of the formula I and/or formula II prepd. by exposing a compd. of the formula I and/or formula II (wherein R1 is H, a lower alkyl, or a lower alkoxy) to light in an org. solvent and/or a compd. of the formula I and/or formula II. A binder resin used for preparing the aforesaid memory material include methyl poly(meth)acrylate/styrene copolymer. The aforesaid compd. or an endoperoxide thereof is mixed in an amt. of pref. 1-50pts. based on 100pts. resin. |
