    Abstract: An imaging method utilizing an imaging member containing a supporting substrate, a layer of a charge carrier injecting surface, a hole blocking layer, an optional adhesive layer, a layer of a charge carrier transport material, a layer of an charge carrier generating material, an optional charge trapping layer, a crossed linked silicone rubber, and an electrically insulating overcoating layer. The member is first charged with electrostatic charges of a first polarity, charged a second time with electrostatic charges of a polarity opposite to said first polarity in order to substantially neutralize the charges residing on the electrically insulating surface of the member and exposed to an imagewise pattern of activating electromagnetic radiation whereby an electrostatic latent image is formed. The electrostatic latent image may be developed to form a visible image which may be transferred to a receiver member. The imaging member may be reused after erasure and cleaning.

    Abstract: An allyloxymethylatedpolyamide composition is disclosed, the allyloxymethylatedpolyamide being represented by Formulae I and II: wherein: n is a positive integer sufficient to achieve a weight average molecular weight between about 5000 and about 100,000, R is an alkylene unit containing from 1 to 10 carbon atoms, between 1 and 99 percent of the R2 sites are -H, and between 1 and 99 percent of the R2 sites are -H, and the remainder of the R2 sites is between 25 percent and 99 percent -CH2-O-(CH2)w-CH=CH2, wherein w is 1, 2 or 3, between 1 and 75 percent of the R2 sites are -CH2-O-R5, and R5 is an alkyl unit containing 1 to 4 carbon atoms, and wherein: m is a positive integer sufficient to achieve a weight average molecular weight between about 5000 and about 100,000, R1 and R are independently selected from the group consisting of alkylene units containing from 1 to 10 carbon atoms, between 1 and 99 percent of the R3 and R4 sites are -H, and between 25 percent and 99 percent of the remainder of the R3 and R4 sites are -CH2-O-(CH2)w-CH=CH2, wherein w is 1, 2 or 3, and between 1 percent and 75 percent of the R2 sites are -CH2-O-R5 wherein R5 is an alkyl unit containing 1 to 4 carbon atoms. The allyloxymethylatedpolyamide may be synthesized by reacting an alcohol soluble polyamide with formaldehyde and an allylalcohol. The allyloxymethylatedpolyamide may be cross linked by a process selected from the group consisting of (a) heating an allyloxymethylatedpolyamide in the presence of a free radical catalyst, and (b) hydrosilation of the double bond of the allyloxy group of the allyloxymethylatedpolyamide with a silicon hydride reactant having at least 2 reactive sites. A preferred article includes a substrate, at least one photoconductive layer, and an overcoat layer comprising a hole transporting hydroxy arylamine compound having at least two hydroxy functional groups, and a cross linked allyloxymethylatedpolyamide film forming binder. A stabilizer may be added to the overcoat.

    Abstract: An electrophotographic imaging member comprising a substrate, a charge generating layer, a charge transport layer, and an overcoat layer comprising a small molecule hole transporting triphenylmethane having at least one hydroxy functional group and a polyamide film forming binder capable of forming hydrogen bonds with the hydroxy functional groups of the hydroxy triphenyl methane. This overcoat layer may be fabricated using an alcohol solvent. This electrophotographic imaging member may be utilized in an electrophotographic imaging process.
