Gas-barrier multilayer film

A process for producing a multilayer film which, even when bent, is less apt to decrease in barrier property or electrical conductivity. The process comprises forming a barrier film and a transparent conductive film on a resin film to produce a multilayer film. The barrier film is formed by a plasma enhanced CVD method which uses electric discharge between rolls. The transparent conductive film is preferably formed by physical vapor deposition. The resin film preferably is a polyester resin film or a polyolefin resin film.

Method of manufacture of multilayer film

An objective of the present invention is to provide a substrate that can achieve high light extraction efficiency, and to provide an organic EL light-emitting apparatus with high light-emitting efficiency by using such a substrate. The present invention is a substrate () comprising a transparent substrate () and a light-concentrating structural body layer (), wherein the light-concentrating structural body layer () includes a plurality of structural bodies () having a conic shape or a hemispherical shape, with the bottom faces of the plurality of structural bodies () having a conic shape or a hemispherical shape being located on the same plane. The structural body () is preferably a structural body having a cone shape, a square pyramid shape or a triangular pyramid shape.

Bio-degradable resin composition, film and shaped article

A gas barrier resin composition or its film having very high level gas barrier and moisture barrier properties, which includes at least a high hydrogen-bonding resin and a non-film-forming inorganic laminar compound having a particle size of 5 .mu.m and an aspect ratio of 50-5,000. The resin composition or its film can be produced by dispersing a non-film-forming inorganic laminar compound in a high hydrogen-bonding resin or resin solution in such a state that the non-film-forming inorganic laminar compound is swollen or cloven with a solvent, and removing the solvent from the dispersion, if necessary in the form of a film, while maintaining the state.
