摘要： An improved overcoat layer for an organic photoconductor drum of an electrophotographic image forming device and method to make the same is provided. The overcoat layer is prepared from a curable composition including a crosslinkable hole transport molecule containing four radical polymerizable functional groups in combination with a crosslinkable acrylate having at least 6 functional groups. This overcoat layer improves wear resistance of the photoconductor drum without negatively altering the electrophotographic properties.
