Abstract
According to the present invention, there is provided an adhesive resin composition comprising 50-99% by weight of a modified hydrogenated block copolymer (a), which is obtained by hydrogenating a block copolymer of a vinyl aromatic compound and a conjugated diene compound followed by modification with an unsaturated carboxylic acid or a derivative thereof, wherein the content of the unsaturated carboxylic acid or the derivative thereof is 0.01-20% by weight, and 1-50% by weight of a tackifier (b), and a laminate and an oriented film wherein such adhesive resin composition is used for the adhesive layer. The adhesive resin composition of the present invention is useful in various fields such as film packaging of foods and pharmaceutical preparations.
