Claim Text:
1. An adhesive resin composition, essentially comprising: a base resin which comprises (A) 30 to 90 parts by weight of a modified ethylene-propylene copolymer, and (B) 70 to 10 parts by weight of a styrene thermoplastic elastomer, provided that (A)+(B) equals 100 parts by weight; and (C) a tackifier in an amount of 30 to 60 parts by weight per 100 parts by weight of the base resin, the modified ethylene-propylene copolymer being one which has been graft-modified with (a) an unsaturated carboxylic acid or a derivative thereof and (b) an aromatic vinyl monomer, comprises 0.1% to 5% by weight of (a) the unsaturated carboxylic acid or the derivative thereof, and has a melting point peak in a range of 100 to 150° C. with an enthalpy of crystal fusion of 0.5 to 10 J/g sas determined by DSC.
