Provided are an adhesive including a polyisocyanate composition (X) containing a polyisocyanate (A), and a polyol composition (Y) containing a tertiary amine compound (B) having plural hydroxyl groups, a polyol (C), and an aliphatic cyclic amide compound (D), as essential components, a laminated film using the adhesive, and a method for producing a laminated film including a step of separately applying two components, which includes bringing a polyisocyanate composition (X) containing a polyisocyanate (A) that is applied onto one base material into contact with a polyol composition (Y) containing a tertiary amine compound (B) having plural hydroxyl groups, a polyol (C), and an aliphatic cyclic amide compound (D) that is applied onto the other base material, and performing pressure-bonding.

Adhesive, laminated film, and production method for laminated film

A two-component curing adhesive using a curing reaction between a polyisocyanate composition (X) and a polyol composition (Y), wherein the polyisocyanate composition (X) includes a polyisocyanate (A), the polyol composition (Y) includes a polyol (B) and a polyamine (C), the polyamine (C) includes a compound having two or more &#x2014;NHgroups in a molecule thereof, and the polyisocyanate composition. (X) and the polyol composition (Y) each have an elongational viscosity of 0.1 to 10 Pa&#xb7;s.

Two-component curing adhesive, laminated film, laminated film-manufacturing apparatus, and method for manufacturing laminated film

Provided is a solvent-free-adhesive polyisocyanate composition, containing, a polyisocyanate (A) and an aromatic vinyl-maleic anhydride copolymer (B), which is a copolymer of aromatic vinyl and maleic anhydride in which a molar ratio [aromatic vinyl/maleic anhydride] of the raw material monomers of the copolymer is 1.5/1 to 5/1. Further provided is a method for producing the polyisocyanate composition; a solvent-free adhesive containing, the solvent-free-adhesive polyisocyanate composition and a polyol (Y); and a multilayer film obtained by laminating a first base material film, a second base material film, and an adhesive layer between the base material films, in which the adhesive layer is formed of the solvent-free adhesive.
