Abstract
An imaging member for ink-based digital printing having an outermost layer including a structured organic film (SOF) having a plurality of segments and a plurality of linkers arranged as a covalent organic framework, wherein the structured organic film may be multi-segment thick.
Claims24
An imaging member for ink-based digital printing comprising:
- a substrate;
- a charge generating layer;
- a charge transport layer;
- and
- an optional overcoat layer;
- wherein an outermost layer of the imaging member is an imaging surface that comprises a structured organic film (SOF) comprising a plurality of segments including at least a first segment type and a plurality of linkers including at least a first linker type arranged as a covalent organic framework (COF), wherein the first segment type and/or the first linker type comprises at least one atom that is not carbon.
