    摘要： A thermal ink-jet printhead includes ejectors which define channels for the passage of liquid ink therethrough. A heating element (60) for nucleating liquid ink is disposed in a heating portion (20) of each channel. A nozzle portion (22) of the channel is smaller in cross-sectional area than the heating portion (20), and a manifold portion (24), through which new liquid ink enters the heating portion (20), is larger in cross-sectional area than the heating portion (20). The design is advantageous for ejecting inks of viscosity greater than 2 centipoise.

    摘要： An imaging member comprised of an optional supporting substrate (1); a ground plane layer (3); a blocking layer (5); an optional adhesive layer (6); a photogenerator layer (7); and a charge-transport layer (9), wherein the blocking layer is comprised of a polyurethane of the formula:
    wherein A is a trivalent group; A′ is a bivalent group; R is alkylene, substituted alkylene, arylene, or substituted arylene; and x and y are number mole fractions of which the sum is equal to 1.0.

    摘要： An electrophotographic imaging member including a supporting substrate, an electrically conductive layer including at least a partially cross-linked polymer having a backbone derived from an alkyl acrylamidoglycolate alkyl ether, a charge blocking layer including a polymer having a backbone also derived from an alkyl acrylamidoglycolate alkyl ether and at least one photoconductive layer. Preferably, the backbone derived from an alkyl acrylamidoglycolate alkyl ether is a copolymer of methyl acrylamidoglycolate methyl ether and a vinyl hydroxy ester or vinyl hydroxy amide. This imaging member may be prepared by a coating process and employed in an electrostatographic imaging process.
