Abstract
A gas barrier film comprises a thermoplastic resin substrate and on the substrate a gas barrier coating, which coating comprises a water soluble or water dispersible high polymer and inorganic stratified particles. In one film, the surface of the gas barrier coating remote from the substrate has a roughness parameter Rt/Ra of 25 or less. In an alternative film, the gas barrier coating contains an amine compound represented by the following general formula: ##STR1## where R1 stands for a hydrogen atom, or a C.sub.1-6 alkyl or allyl or phenyl group; R2 stands for a hydrogen atom, or an optionally substrated alkyl or allyl group; and R3 stands for an optionally substituted alkyl or allyl group.
