Abstract
Provided are an adhesive resin laminate having an excellent adhesive force to two adherends, a laminate in which this adhesive resin laminate is laminated with two adherends, and a method of producing them. An adhesive resin laminate having at least a first adhesive layer and a second adhesive layer, in which the first adhesive layer includes a base resin and a crosslinking agent, the base resin is a modified polyolefin resin, the crosslinking agent is an epoxy-based compound, the second adhesive layer includes a polyolefin-based resin, and the first adhesive layer has a viscoelastic modulus measurement value E (150) at 150° C. of 1.0×104 Pa or more and 1.0×108 Pa or less.
Claims8
An adhesive resin laminate having at least a first adhesive layer and a second adhesive layer,
- wherein
- said first adhesive layer comprises a base resin and a crosslinking agent, said base resin is a modified polyolefin resin, and said crosslinking agent is an epoxy-based compound,
- said second adhesive layer comprises a polyolefin-based resin, and
- said first adhesive layer has a viscoelastic modulus measurement value E (150) at 150° C. of 1.0×104 Pa or more and 1.0×108 Pa or less.
A laminate, comprising:
- an adhesive resin laminate having at least a first adhesive layer and a second adhesive layer;
- and
- first and second adherends,
- the adhesive resin laminate and the first and second adherends being laminated in an order of the first adherend, said first adhesive layer of said adhesive resin laminate, said second adhesive layer of said adhesive resin laminate, and the second adherend, wherein
- said first adhesive layer comprises a base resin and a crosslinking agent, said base resin is a modified polyolefin resin, and said crosslinking agent is an epoxy-based compound,
- said second adhesive layer comprises a polyolefin-based resin, and
- said first adhesive layer has a viscoelastic modulus measurement value E (150) at 150° C. of 1.0×104 Pa or more and 1.0×108 Pa or less.
