Plastic substrate coating method for manufacture of display plates or lenses involves plasma enhanced chemical vapor deposition application of an intermediate layer onto a substrate before application of functional layers

摘要

An intermediate layer(2) is applied onto the substrate(1) by a PECVD(plasma enhanced chemical vapor deposition) process which subjects the substrate to very low energy levels. A functional layer(3) is then applied on top of the intermediate layer. Independent claims are also included for: (a) the process equipment; and (b) a coated product produced by the process and comprising a plastic substrate(1), an intermediate layer(2) and one or more functional layers(3).
