    • 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.

    • Process for preparation of 2-anthryl and substituted 2-anthryl functional monomers and polymers. In the process for preparation of these monomers, an anthracenic reactant of the formula: ##STR1## wherein X and Y are independently selected from hydrogen, chlorine, bromine, alkyl of 1 to 4 carbon atoms or phenylIs acylated in nitrobenzene under conditions which favor reaction at the two position. The resulting acylated product can then be (a) reacted with an alkylidenephosphorane (Wittig synthesis) or (b) reduced to the corresponding alcohol. Subsequent to such reduction, this alcohol can undergo further modification at the hydroxyl function to form a polymerizable addition monomer. Through the proper selection of the relative concentration of reactants and control over processing conditions, it is possible not only to prepare such monomers in high yields but also upon polymerization of such monomers, to obtain high molecular weight 2-anthryl and substituted 2-anthryl functional polymers (molecular weight of at least 10.sup.4). Polymers of such high molecular weight can readily be formed without the use of binders into self-supporting films. Such films are intrinsically photoconductive in the ultraviolet region of the electromagnetic spectrum and have good transport capabilities for charge carriers of both polarities.
