摘要:
The present invention is a method of depositing a lubricating layer on an imaging element. The method includes providing a polymer or a wax selected from the group consisting of polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), fluorinated ethylene copolymers, polyethylenes, high density polyethylene, natural waxes such as Carnauba wax, synthetic waxes, and silicone waxes in a deposition chamber. The chamber is evacuated to a pressure of 10−1 Torr or less. A carrier gas, preferably selected from N2, O2, Ar, is bled into the chamber while maintaining the pressure in the chamber to 100 mTorr or less. The polymer or wax is heated to a temperature sufficient to vaporize the polymer or wax, and the imaging element is continuously moved through the chamber depositing the polymer or wax on the imaging element to form the lubricating layer.
