ELECTROPHOTOGRAPHIC SENSITIVE BODY FOR POSITIVE CHARGING |
摘要 |
PURPOSE:To improve the scratch resistance and durability and to provide superior resistance to oxidation by ozone by incorporating an electric charge transferring substance into the electric charge generating layer and a specified compd. into the generating layer or the protective layer. CONSTITUTION:An electric charge transferring layer 2 and an electric charge generating layer 3 are laminated on an electrically conductive support 1 an a protective layer 7 is formed on the layer 3 as required. The electric charge generating layer 3 contains an electric charge transferring substance 5b and the layer 3 or the protective layer 7 contains a compd. represented by formula I (where each of R1-R3 is 1-4C alkyl). When the substance 5b is a styryl or hydrazone compd. and the thickness of the layer 3 is 2-7mum, a more significant effect is shown. Since the compd. represented by the formula I prevents the deterioration of the substance 5b by ozone by self-oxidation, the compd. is preferably incorporated into the protective layer 7 formed on the layer 3 as required but it may be incorporated into the layer 3 or may be further incorporated into the layer 2. |
