Abstract

Provided is a thermoplastic resin composition or an adhesive coating material capable of adhering a cyclic polyolefin-based polymer with a metal or metal compound such as aluminum foil or an ethylene-vinyl alcohol copolymer with sufficient strength. The thermoplastic resin composition contains (A) 100 parts by mass of thermoplastic resin; (B) 0.05 to 5 parts by mass of one or more kinds selected from the group consisting of an unsaturated carboxylic acid and an unsaturated carboxylic acid derivative; and (C) 0.01 to 3 parts by mass of organic peroxide; which component (A) contains (a1) 10 to 90% by mass cyclic polyolefin-based polymer; and (a2) 90 to 10% by mass a hydrogenated product of a block copolymer comprising a polymer block composed mainly of an aromatic vinyl compound and a random copolymer block of a conjugated diene compound and an aromatic vinyl compound (with the proviso that the total of the component (a1) and the component (a2) is 100% by mass).
