    • A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises a photoconductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises an electrically inactive organic resinous material containing from about 10 to about 75 percent by weight of: ##STR1## R.sub.1 is selected from the group consisting of hydrogen (ortho) CH.sub.3, (meta) CH.sub.3, (para) CH.sub.3, and R.sub.2 is selected from the group consisting of hydrogen, (ortho) CH.sub.3, (meta) CH.sub.3, and (para) CH.sub.3. The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.
    • 公开了具有至少两个电操作层的感光构件。 第一层包括光电导层,其能够对空穴进行光生并将光生空穴注入连续的电荷传输层。 电荷输送层包含含有约10至约75重量%的电惰性有机树脂材料:R 1选自氢(邻)CH 3,(间)CH 3,(对)CH 3, 并且R 2选自氢,(邻)CH 3,(甲基)CH 3和(对))CH 3。 在预期用途的光谱区域中基本上不吸收的电荷输送层是“活性的”,因为其允许从光电导层注入光生孔,并允许这些孔传输通过电荷输送层。 该结构可以以通常包括充电,曝光和显影的常规静电复印模式成像。

    • A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises a photoconductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises an electrically inactive organic resinous material containing from about 15 to about 75 percent by weight of N,N'-diphenyl-N,N'-bis(phenylmethyl)-[1,1'-biphenyl]-4,4'-diamine. The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer.

    • Method for achieving free radical initiated copolymerization of an addition monomer having pendant therefrom a strong donor group with an addition monomer having pendant therefrom a strong acceptor group. Copolymers prepared according to this method can be represented by the following formula: ##STR1## wherein R is hydrogen or methyl;R' is hydrogen or methyl;R" is hydrogen or methyl;R'" is selected from the group consisting of --NO.sub.2, halogen, --CN and --CF.sub.3 ;X and Y are independently selected from the group consisting of hydrogen, chlorine, bromine, alkyl of 1 - 4 carbon atoms and phenyl;a and b can range from 0 - 4; andn and m can range from about 5 to about 95 percent.The polymeric compositions prepared according to this method are suitable for use in electrophotography either alone as the primary photoresponsive entity or in combination with other photoconductive materials.
