Photoconductor having protective overcoat layer with a charge transport molecule with four radical polymerizable hydrophilic functional groups containing an oxygen atom and method of making the same

摘要

An improved organic photoconductor drum used in an electrophotographic image forming device and method to make the same is provided. The organic photoconductor drum contains a protective overcoat. The protective overcoat is prepared from a curable composition including a charge transport molecule containing four radical polymerizable hydrophilic functional groups containing an oxygen atom of the general structure shown below:; where R₁ and R₂ contain a spacer group and a radical polymerizable hydrophilic functional group containing an oxygen atom, R₃ and R₄ are a non-radical polymerizable functional group, and R₅ and R₆ contain a spacer group and a radical polymerizable hydrophilic functional group containing an oxygen atom. The curable composition may also contain at least one curing agent. This organic photoconductor drum has excellent wear resistance without negatively altering the electrophotographic properties, thus protecting the organic photoconductor drum from damage and extending its service life.
