Claim 8
Dependent Claim
109 words
An electrophotographic imaging process comprising the steps of a. providiNg an electrophotographic plate comprising an electrically conductive substrate material, said substrate being overcoated with an interlayer material selected from the group consisting of n-dimethoxymethylsilylisobutylethylenediamine; n-trimethoxysilylisobutylethylenediamine; about 2 parts, by weight, of n-dimethoxymethylsilylisobutylethylenediamine and about 1 part, by weight, of gamma-methacryloxypropyltrimethoxysilane; about 2 parts, by weight, of n-dimethoxymethylsilylisobutylethylenediamine and about 1 part, by weight, of vinyltriacetoxysilane and mixtures thereof, said interlayer, in turn, being coated with an overlayer comprising selenium; b. forming an electrostatic latent image on said plate; and c. contacting said latent image with electroscopic marking material whereby a visible image corresponding to said latent image is produced.
Claim 9
Dependent Claim
33 words
The electrophotographic imaging process of claim 9 wherein said electrostatic image is formed by uniformly electrostatically charging the surface of said plate and exposing said plate to an image of activating electromagnetic radiation.
Claim 10
Dependent Claim
57 words
The electrophotographic imaging process of claim 9 wherein said overlayer is selected from the group consisting of selenium, mixtures of arsenic and selenium, mixtures of tellurium and selenium, mixtures of sulfur and selenium, mixtures of cadmium, sulfur, and selenium, mixtures of cadmium and selenium, arsenic selenide, tellurium selenide, sulfur selenide, cadmium selenide, cadmium sulfo-selenide, and mixtures thereof.
