It is an object of the invention to provide polypropylene adhesives which have excellent adhesion to polar materials and exhibit particularly excellent adhesion after high-speed cast film processing, stretching or extrusion coating, and are excellent in blushing resistance, and multilayer structures having the adhesives. The adhesive resin composition is a grafted resin composition comprising a polypropylene component (A), an ethylene/propylene/alpha-olefin copolymer component (B), an ethylene/alpha-olefin copolymer component (C), and an unsaturated carboxylic acid and/or a derivative thereof (D), and which contains the component (A) at 5 to 80 parts by mass, the component (B) at 5 to 70 parts by mass and the component (C) at 1 to 40 parts by mass based on 100 parts by mass of the components (A), (B) and (C) combined and has an ethylene/propylene/alpha-olefin ratio in n-decane-soluble components of 5-95/5-95/1-50 mol % and a graft ratio of 0.01 to 5 wt %.
