PURPOSE:To form the subject body with high sensitivity by incorporating a specified compd. in the sensitive body. CONSTITUTION:The compd. shown by formula I is incorporated in the sensitive body. In formula I. R is alkyl or alkoxy group or halogen atom. The concrete example shown by formula I is exemplified by a compd. shown by formula II. As the compd. shown by formula I plays a role of the excellent effective component of the sensitive body, the sensitive body which has the high sensitivity, and a low residual voltage and the excellent durability, is formed. |
