Claims
- 1. A process for preparing an electrophotographic imaging member comprising the steps of:
- a) providing a supporting substrate having a conductive layer and a charge blocking layer;
- b) coating said substrate with a film forming photoconductive dispersion comprising photoconductive particles made of benzimidazole perylene and a dispersion medium consisting essentially of a polymerizable film forming vinyl monomer;
- c) polymerizing said photoconductive film forming dispersion by autocatalysis to form a charge generating layer; and
- d) forming a charge transport layer on top of said charge generating layer.
- 2. The process of claim 1 wherein said vinyl monomer is selected from the group consisting of cyclic vinyl monomers and alkaline vinyl monomers.
- 3. The process of claim 2 wherein said vinyl monomer is a cyclic vinyl monomer selected from the group consisting of 5-vinyl-2-norbornene and vinyl benzene.
- 4. The process of claim 2 wherein said vinyl monomer is an alkaline vinyl monomer selected from the group consisting of 4-vinylpyridine and vinyl pyrrolidone.
- 5. The process of claim 1 wherein said dispersion further comprises a reactive low molecular weight polymer.
- 6. The process of claim 5 wherein said polymer is selected from the group consisting of urethane polyesters, polyethers and epoxides.
