Abstract
A two-component curable solventless adhesive which enables a laminated composite film comprising a barrier layer and a plastic film laminated with each other to maintain excellent appearance and adhesive strength for a long period even after a sterilization treatment at high temperature, and to appropriately adjust a reaction between a base resin and a curing agent during a production of the laminated composite film. The two-component curable solventless adhesive comprises a base resin and a curing agent, wherein the base resin contains a polyol having an acid group and a secondary or tertiary terminal hydroxyl group accounting for 30% or more of the entire terminal hydroxyl groups of the polyol, and the curing agent contains an isocyanate group-terminated urethane prepolymer containing at least an aralkyl polyisocyanate and/or a modified substance thereof as a raw polyisocyanate, and a content of a low molecular weight polyisocyanate is defined.
