Polymer composition for lamination and laminated body using same

A polymer composition for lamination characterized in that the composition:

• consists of
• (X1) 100 to 60% by weight of an ionomer characterized in that at least a part of a carboxyl group and/or a dicarboxylic anhydride group in a copolymer (P) containing a structural unit (A) derived from ethylene and/or an α-olefin having 3 to 20 carbon atoms and a structural unit (B) derived from a monomer having a carboxyl group and/or a dicarboxylic anhydride group as essential constitutional units being converted into a metal-containing carboxylic acid salt containing at least one kind of a metal ion(s) selected from Group 1, Group 2 or Group 12 of the periodic table, and a phase angle δ of the ionomer at an absolute value G*=0.1 MPa of a complex modulus of elasticity measured by a rotary rheometer is a range of 50 degrees to 75 degrees, and
• (X2) 40 to 0% by weight of an ethylene-based copolymer containing ethylene by high-pressure radical polymerization as an essential monomer, and has a melt flow rate of 1.0 to 100 g/10 min.
