    摘要： A resin composition comprising 100 parts by weight of an aggregated inorganic layer compound and 200-10,000 parts by weight of a resin, the particle size of the aggregated inorganic layer compound satisfying the mathematical expressions (1): 5 wherein L is the average particle diameter of the inorganic layer compound before aggregation and D is the average particle diameter of the inorganic layer compound after aggregation (average aggregated particle diameter), and a process for producing the resin composition described above which comprises a process of dispersing the inorganic layer compound in a dispersion medium to obtain a liquid dispersion of the inorganic layer compound,
       a process of aggregating the inorganic layer compound present in the liquid dispersion obtained by process 1,
       and a process of compounding the liquid dispersion of the inorganic layer compound aggregated by process 2 with the resin.
    The resin composition of the present invention is excellent in gas barrier property, particularly in oxygen barrier property.

    摘要： A gas barrier resin composition or its film having very high level gas barrier and moisture barrier properties, which comprises a resin and an inorganic laminar compound having a particle size of 5 µm and an aspect ratio of 50-5,000. Said resin composition or its film can be produced by dispersing an inorganic laminar compound in a resin or resin solution in the state that the 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 keeping said state.
