摘要:
A composition is provided for coating a photoreceptor having a charge generating layer and a charge transport layer. The composition includes a hole transport material, a cross-linkable film forming binder having at least one functional group that is reactive with isocyanate, a blocked isocyanate cross-linking agent and a solvent having a boiling point equal to or below the deblocking temperature. The blocked isocyanate cross-linking agent is the reaction product of an isocyanate and a blocking agent, wherein the blocking agent has a boiling point temperature equal to or below a selected deblocking temperature to allow the isocyanate to form cross-links. The invention also provides an electrophotographic imaging member with an overcoat layer comprising a cross-linked film forming binder, an isocyanate compound, a hole transport material, and optionally a surface energy reducing agent. Processes for making the imaging members are also provided.
