International Classification:

G03G 5/14

US Classification:

430060000, 430131000

Abstract:

Provided is an imaging member comprising a substrate, an undercoat layer (UCL), a charge generation layer, a charge transport layer, and an optional overcoat layer. The undercoat layer is formed from a single-phase UCL coating formulation comprising an organic titanate, a polymer containing active hydrogen, and an aminosilane. The UCL formulation has improved properties such as stability, processing convenience, and longer pot life etc. The UCL formulation can be used to manufacture an imaging member such as photoreceptor with improved properties such as stable, thick UCL coating, resistance to electrical failure, and PIDC independency on UCL thickness etc.

International Classification:

B05D001/18

US Classification:

427/430100

Abstract:

A method for dip coating the exterior surface of a hollow substrate having an open first end and an open second end, the method including: (a) inserting a chuck assembly through the open first end into the substrate interior, wherein the chuck assembly includes a width changing apparatus and a polymeric member coupled to the width changing apparatus, wherein the chuck assembly defines a space that communicates with the substrate interior but is otherwise enclosed, wherein the space includes (i) a chamber and (ii) a passageway through a portion of the chuck assembly that permits the substrate interior to communicate with the chamber, wherein the width changing apparatus is disposed in the passageway but still allows airflow between the substrate interior and the chamber; (b) holding the substrate with the chuck assembly wherein the polymeric member forms a hermetic seal with the substrate; (c) contacting the substrate with a coating solution, starting from the second end, while the chuck assembly holds the substrate and the hermetic seal is maintained between the polymeric member and the substrate, wherein there is a closed area into which vapor from the coating solution can flow and the closed area is defined by the space of the chuck assembly and the substrate interior; and (d) separating the substrate and the coating solution to leave a layer of the coating solution on the exterior surface of the substrate.
