    摘要： A fuser belt for an electrostatographic device and methods for making the fuser belt can include the use of a polyimide and a plurality of copper nanoparticles. The use of copper nanoparticles can result in a fuser belt having a lower heat capacity and a higher thermal conductivity than conventional fuser belts.

    摘要： The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. Embodiments pertain to an improved electrostatographic imaging member comprising an interfacial layer further comprising an opaque semi-crystalline polyester resin that is also a hot-melt adhesive to prevent light transmission to the substrate and thus significantly reduce “plywood effect,” a print quality defect.

    摘要： A compound of the formula wherein R1, R2, R3, and R4 can be the same or different, and wherein each of R1, R2, R3, and R4 are independently selected from (i) hydrogen, (ii) an alkyl group, (iii) an aryl group, (iv) an arylalkyl group, (v) an alkylaryl group, (vi) an alkoxy group, (vii) an aryloxy group, (viii) an arylalkyloxy group, (ix) an alkylaryloxy group; and wherein R5 is (i) an alkylene group, (ii) an arylene group, which can be substituted or unsubstituted arylene, and wherein hetero atoms may optionally be present in the arylene group, (iii) an arylalkylene group, or (iv) an alkylarylene group. Further, a process for preparing a charge transport compound comprises contacting a hydroxy-functionalized triarylamine with a dihalide in an alkaline-water solution at room temperature; wherein the raw material for the dihalide comprises a purified or recovered halogen-organic solvent-containing waste stream.
