Alumnus Damodar Pai: scientist and inventor

Disclosed is a process for the preparation of poly(vinylbenzyl alcohol) by, for example the hydrolysis of poly(vinylbenzyl acetate) in the presence of a basic catalyst in an organic solvent.

Polymer processes

A method for forming images including a) depositing an electrostatic latent image on a charge retentive surface of a photoreceptor member having a substrate; a charge transport layer with charge transport materials; and an overcoat layer positioned on the charge transport layer, wherein the overcoat layer includes a crosslinkable alcohol-soluble polyamide; and wherein the overcoat layer further includes additives having titanium dioxide, silica, a crosslinking agent, a deletion control agent, and a charge transport molecule; and b) applying a developer material via a development component to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface, wherein the developer material comprises emulsion aggregation toner, and further wherein at least one of the additives create a texturized surface on the charge retentive surface thereby reducing the contact area between the emulsion aggregation toners and the charge retentive surface enabling increased cleaning of toners.

Method for imaging with imaging member having filled overcoat layer

A seamed flexible belt having a substrate and a seam having interlocking seam members, wherein the interlocking seam members are held together by an adhesive having polyamide and an optional electrically conductive filler, for use in electrostatographic, contact electrostatic, digital and other like printing machines.

Imageable seamed belts having polyamide adhesive between interlocking seaming members

A photoconductive imaging member comprised of an optional supporting substrate, a hole blocking layer thereover, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer is comprised of a pyrolyzed polyacrylonitrile.

Photoconductive imaging members having pyrolyzed polyacrylonitrile hole blocking layer

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.

Imaging member

A charge transport layer for an imaging member comprising a first and second charge transport layer wherein the second charge transport layer comprises a charge transport component, a hindered phenol covalently bonded to a polymer, and an additional polymer binder other than the polymer containing the hindered phenol. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and excellent print quality.

Photoconductive imaging members having pyrolized polyacrylonitrile hole blocking layer

A charge transport layer for an imaging member comprising a charge transport layer wherein the charge transport layer is coated in two passes and wherein the second pass comprises the application of a charge transport component and a hindered phenol covalently bonded to a polymer. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and excellent print quality.

A photoconductive imaging member is disclosed comprising a charge generation layer and a charge transport layer comprising an oxidative inhibitor. An electrophotographic imaging process using the imaging member of the invention is also described.

Dual charge transport layer and photoconductive imaging member including the same

A charge transport layer for an imaging member comprising a dual charge transport layer and wherein the charge transport layers comprise a photogenerating layer; (1) a first charge transport layer comprised of a charge transport component and a resin binder; and thereover and in contact with the first layer; (2) a second top charge transport layer comprised of a charge transport component, a resin binder and a hindered phenol dopant. The charge transport layer exhibits, excellent electrical performance, outstanding print quality and reduces the diffusion of the anti-oxidant into the charge generator layer.

An adhesive having polyamide and an electrically conductive filler dispersed or contained therein, for use in bonding components of electrostatographic, contact electrostatic, digital and other like printing machines.

Polyamide and conductive filler adhesive

A coated transport roll comprised of a core with a coating comprised of a charge transporting polymer and an oxidizing agent.

Development system coatings

Purification process

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.
