Claim Text:
1. An overcoat layer for an organic photoconductor drum, comprising a curable composition including: about 20 to about 80 percent by weight of a charge transport molecule containing four radical polymerizable functional groups as exemplified below: where R 1 and R 2 contain a spacer group and a radical polymerizable functional group, R 3 and R 4 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 R 5 and R 6 contain a spacer group and a radical polymerizable functional group; and about 20 to about 80 percent by weight of a curing agent having a urethane resin containing six radical polymerizable functional groups, wherein the radical polymerizable functional group of R
