Kind Code:
B2
Abstract:
Provided is a reactive adhesive which comprises a polyol component A containing a polyol compound and an isocyanate component B containing an isocyanate compound, and wherein: the isocyanate component B contains a reaction product (B-1) of a polyol and an isocyanate and a reactive diluent (B-2) having an isocyanate group that has a number average molecular weight within the range of 400-1,000; and the viscosity as determined by blending the polyol component A and the isocyanate component B at the weight ratio and leaving the resulting blend to stand for 30 minutes in an atmosphere at 40°C is 5,000 mPa·s or less. Also provided are a multilayer film and a package. It is preferable that the reactive diluent (B-2) having an isocyanate group is an aromatic diisocyanate, an aliphatic diisocyanate, or a dimer or trimer of one of these diisocyanates.
