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 when an adhesion initiation temperature of the first adhesive layer is set to T1, and an adhesion initiation temperature of the second adhesive layer is set to T2, T2 is higher than T1 by 30° C. or more.
Claims6
An adhesive resin laminate consisting essentially of a first adhesive layer and a second adhesive layer,
- wherein
- said first adhesive layer comprises a base resin and a crosslinking agent, in which a maleic acid anhydride-modified propylene-1-butene copolymer is contained as said base resin with a ratio of 98 to 99.99 parts by mass, and a phenol novolak epoxy resin having a bisphenol skeleton is contained as said crosslinking agent with a ratio of 0.01 to 2 parts by mass,
- said second adhesive layer comprises a layer composed of block polypropylene and a layer composed of random polypropylene, wherein the layer composed of random polypropylene is in contact with a surface of said first adhesive layer, and
- when an adhesion initiation temperature of said first adhesive layer is set to T1, and an adhesion initiation temperature of said second adhesive layer is set to T2, T2 is higher than T1 by 30° C. or more.
