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 < D/L and 1 µm < D < 1,000 µm (1) 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 (hereinafter referred to as process 1), a process of aggregating the inorganic layer compound present in the liquid dispersion obtained by the process 1 (hereinafter referred to as process 2), and a process of compounding the liquid dispersion of the inorganic layer compound aggregated by the process 2 with the resin (hereinafter referred to as process 3). The resin composition of the present inven- tion is excellent in gas barrier property, particularly in oxygen barrier property.
