Abstract

A charge transport molecule containing four radical polymerizable functional groups used in an overcoat for an organic photoconductor drum of an electrophotographic image forming device is provided. The charge transport molecule containing four radical polymerizable functional groups of the general structure exemplified below: where R1 and R2 contain a spacer group and a radical polymerizable functional group, R3 and R4 are selected from the group consisting of a radical polymerizable functional group, a non-radical polymerizable functional group, and one each of a radical polymerizable functional group and a non-radial polymerizable functional group, and R5 and R6 contain a spacer group and a radical polymerizable functional group.
