Abstract
Environmentally compatible solvents are used in a method for removing coating layers from an electrostatographic imaging member substrate. The solvents include a solution containing at least one member selected from the group consisting of acetic acid, dimethyl malonate and diethyl malonate. The solution is used in a method for removing coating layers from at least part of a substrate, which involves contacting a solution having at least one member selected from the group consisting of acetic acid, dimethyl malonate and diethyl malonate, on at least part of a substrate containing an coating layer until the coating layer is effectively removed from said at least part of the substrate. The environmentally compatible solvents may be used to reclaim pigments in photoconductive coating layers and substrates of defective imaging members during the manufacturing process, or after the operational life of electrostatographic imaging members has expired.
