To provide adherent resin compositions for obtaining laminated products improved in gas barrier properties, mechanical strength, resistance to contents, designing, and the like.

Adherent resin compositions comprise (a) a modified ethylene type polymer modified with 0.01-10 wt.% unsaturated carboxylic acid or a derivative thereof which has an MFR of 0.05-50 g/10 min and a density of 0.880-0.950 g/cm3, (b) a tackifier, and (c) a hydrogenated product of a block copolymer having a vinyl aromatic compound polymer block and a conjugated diene compound polymer block, and meet the formula: Tg1-Tg2≥5 deg (wherein Tg1 is a Tg of the conjugated diene compound polymer block in component (c) by the DSC measurement of the resin composition comprising components (a), (b), and (c); and Tg2 is a Tg of the conjugated diene compound polymer block in the block copolymer by the DSC measurement of component (c) alone, provided that Tg2 ≤-45°C).
