LAMINATE AND METHOD FOR HEAT MELTING ADHESION

摘要

PROBLEM TO BE SOLVED: To provide a laminate of cyclic olefin copolymers which is excellent in heat melting adhesion properties, a method for heat melting adhesion of the laminate, and a method for the heat melting adhesion between an olefin resin and a non-olefin resin. SOLUTION: The laminate of a copolymer (a) comprising 40-95 mole % of a cyclic olefin unit and 5-60 mole % of an ethylene unit and a copolymer layer (b) comprising 5-39.9 mole % of the unit of a cyclic olefin expressed by formula (I) and 60.1-95 mole % of an ethylene unit is provided. The olefin resin is heat melting-adhered to the non-olefin resin by using the laminate.
