Patent ID: 7651741

Claim:
A process of preparing a support comprising a flexible resin substrate and provided thereon, at least two layers containing a metal oxide, a metal nitride or a metal nitride oxide, the two layers being different in carbon concentration, the process comprising exciting a reactive gas at a space between opposed electrodes at atmospheric pressure or approximately atmospheric pressure by electric discharge to be in a plasma state, and exposing the substrate or the layer on the substrate to the reactive gas in the plasma state, wherein the metal oxide is a compound selected from silicon oxide, titanium oxide, indium oxide, tin oxide, indium tin oxide (ITO), or alumina, the metal nitride is a compound selected from silicon nitride or titanium nitride, the metal oxide nitride is silicon oxide nitride, or titanium oxide nitride, and the reactive gas is an organometallic compound or a monomer, and wherein the layer closest to the substrate among the at least two layers contains carbon in an amount from 0.2 to 5% by weight.
