Using for layer (C) this adhesive composition, and as layer (A) saponified ethylene-vinyl acetate copolymer resin containing 56 mol % of vinyl acetate component, and having [η]=0.96 (in the mixture of phenol/water=85/15, at 30° C., dl/g), which was obtained by saponifying 99.5 mol % of vinyl acetate and as layer (B) poly vinyl acetate resin plasticized with 35 wt % of dioctylphthalate, co-extrusion was carried out at a die temperature of 200° C. to obtain a fine laminated article having five layers of three kinds of resin, (B)/(C)/(A)/(C)/(B). The each thickness of layers was 10 μm for (A), 100 μm for (B) and 5 μm for (C). And the article had a good peel strength of (A)/(B); 1.0 kg/cm (T peel test at 200 mm/min).
