Abstract
An overcoat layer for an organic photoconductor drum of an electrophotographic image forming device is provided. The overcoat layer is prepared from a curable composition including a urethane resin having at least six radical polymerizable functional groups. The at least six radical polymerizable functional groups may include acrylate group, methacrylate group, styrenic group, allylic group, vinylic group, glycidyl ether group, epoxy group, or combinations thereof. This overcoat layer has an improved wear resistance, thus protecting the organic photoconductor drum from damage and extending its useful life.
