Abstract
An overcoat layer for an organic photoconductor drum includes a curable composition having about 20 to about 80 percent by weight of a charge transport molecule containing four radical polymerizable functional groups as exemplified below: where R1 and R2 contain a spacer group and a radical polymerizable functional group, R3 and R4 are hydrogen atoms, and R5 and R6 contain a spacer group and a radical polymerizable functional group. The curable composition may also include a non-radical polymerizable additive, such as a surfactant, and/or a curing agent.
