A photoconductor that includes, for example, a supporting substrate, a photogenerating layer, and at least one charge transport layer that contains at least one charge transport component, and where the photogenerating layer contains a hydroxyquinoline.

Hydroxyquinoline containing photoconductors

A photoconductor containing a supporting substrate, a photogenerating layer; and at least one charge transport layer where the photogenerating layer contains a photogenerating pigment and a chelating additive or agent of, for example, a &#x3b2;-diketone, a ketoester, a hydroxyl carboxylic acid, a hydroxyl carboxylic acid ester, a keto alcohol, or an amino alcohol.

Photoconductors containing photogenerating chelating components

A photoconductor containing a supporting substrate, a photogenerating layer; and at least one charge transport layer where the photogenerating layer contains a photogenerating pigment and a chelating additive or agent.

Photoconductors containing chelating components

An imaging member including an optional supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport component, and an overcoating layer in contact with and contiguous to the charge transport, and which overcoating is comprised of an acrylated polyol, a polyalkylene glycol, a crosslinking agent, a hydroxy functionalized siloxane and a charge transport component.

A unique solvent system adapted for high speed overcoat applications is disclosed. The solvent system comprises methyl alcohol and monochlorobenzene in a weight ratio of about 6:1 to about 1.5:1, respectively.

Solvent system for overcoating materials

A filtration system comprising a filter cassette having integrated ultrasonic transducers incorporated therein, and a method for using the same. The integrated system of filters and transducers can be hardened for use in hazardous environments, and is particularly suitable for the implementation of sonication in cross flow filtration processes further integrated with a manufacturing process. The system provides cost savings both in terms of less equipment and space for cleaning processes on the manufacturing floor.

Integrated dual cross flow filtration and ultrasonic transducer assembly

An image-bearing article used in liquid contact electrostatic printing (CEP) is formed from polymers that meet the requisite conformance and heat stability for the CEP process. Excessive absorption of toner carrier liquids by the image-bearing article in liquid CEP leads to the deterioration of the image-bearing article and reduces the useful life of the image-bearing article. The absorption of the toner carrier fluid may be controlled by the addition of oxides, silicone elastomers containing phenyl end groups, fluorosilicones or increasing the cross-linking density of the methyl silicones.

A process for preparing a mixed solvent adhesive solution involving mixing an alcohol and an adhesive to form an adhesive solution; mixing a charge transporting molecule and a solvent other than alcohol to form a charge transport solution; mixing the charge transport solution with the adhesive solution to form a mixed solvent solution; mixing an electrically conductive filler and a solvent to form a filled solvent solution; and mixing the filled solvent solution to the mixed solvent solution so as to form a mixed solvent adhesive solution.
