Patent ID: 8871350

Claim:
A gas barrier film comprising a gas barrier layer in direct contact with each of both main surfaces of a plastic film selected from the group of PEN, PET, PI, fluorine resin, PC, PAR, PES, and heat-resistive liquid crystal films, wherein the gas barrier layer is an SiCNFH layer, an SiOCNH layer or an SiCNH layer deposited by Cat-CVD, the SiCNFH layer satisfying conditions of 0.01<I(SiH)/I(SiN)<0.03, 0.00<I(CH)/I(SiN)<0.02, 0.05<I(NH)/I(SiN)<0.08, and 0.05<I(CF)/I(SiN)<0.25; the SiOCNH layer satisfying conditions of 0.1<I(SiH)/I(NH)<0.5, 0.0<I(CH)/I(NH)<0.2, 10<I(SiN)/I(NH)<20, and 2<I(SiO 2 )/I(NH)<5; and the SiCNH layer satisfying conditions of 0.01<I(SiH)/I(SiN)<0.03, 0.00<I(CH)/I(SiN)<0.02 and 0.05<I(NH)/I(SiN)<0.08; where the “I” represents peak intensity of Fourier transform infrared spectroscopy related to the atomic bond shown in the parentheses after the “I”.
