Patent ID: 7157153

Claim:
A support comprising a flexible substrate and provided thereon, one or two or more polymer layers containing a polymeric compound and one or two or more sealing layers containing a metal oxide, a metal nitride or a metal oxide nitride, wherein at least one of the polymer layers and the sealing layers is formed by a 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 the plasma state, and exposing the flexible substrate, the polymer layer, or the sealing layer to the reactive gas in the plasma state, and wherein the polymeric compound is obtained by polymerization of a monomer comprising a vinyl compound or an acetylene compound, 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 a compound selected from silicon oxide nitride, or titanium oxide nitride, and the reactive gas is an organometallic compound or the monomer, and wherein the sealing layer contains carbon in an amount of from 0.2 to 5% by weight.
