<p>PURPOSE:To obtain a charge transfer-type acceptor compd. excellent in stability and safeness which can be used for a positive charge function separation-type photosensitive body by using a specified benzophenone tetracarboxylic acid diimide compd. CONSTITUTION:A benzophenone tetracarboxylic acid diimide compd. expressed by formula is used for a photographic sensitive body. In formula, R is an alkyl group, aralkyl group or aryl group having <=8 carbon number, Rc is a cycloalkylene group or arylene group having >=4 and <=8 carbon number, and A<1>, A<2> are same or different hydrogen atoms, alkyl groups having <=4 carbon number, nitro groups, cyano groups, carboxylic acid ester groups, or halogen atoms. The synthesis of this benzophenone tetracarboxylic acid diimide compd. expressed by formula is not limited but is performed according to a well-known method to synthesize normal carboxylic acid imide.</p> |
