Abstract
The adhesive resin composition of this invention comprises (A) 30 to 70 parts by weight of an ethylene/vinyl acetate copolymer, (B) 0 to 50 parts by weight of an ethylene/&agr;-olefin copolymer having an ethylene content of 30 to 95 mole % and a degree of crystallinity by X-ray of not higher than 40%, (C) 0 to 50 parts by weight of a modified ethylene/&agr;-olefin copolymer having an ethylene content of 30 to 95 mole % and a degree of crystallinity by X-ray of not higher than 40%, (D) 0 to 30 parts by weight of modified polyethylene, (E) 1 to 20 parts by weight of a tackifier and (F) 1 to 20 parts by weight of a styrene polymer, characterized in that (B)+(C)=15 to 60 parts by weight, (C)+(D)≧2 parts by weight, and (A)/[(B)+(C)]=0.5 to 3. This composition has excellent adhesion to the styrene resin or a saponified product of the ethylene/vinyl acetate copolymer, and a laminated body of these resins using this composition as an adhesive layer has excellent post-processability.
