2-COMPONENT CURABLE POLYURETHANE LAMINATE ADHESIVE COMPOSITION, LAMINATE FILM, AND FOOD PACKAGING MATERIAL

摘要

Provided are a 2-component curable polyurethane laminate adhesive composition that exhibits good adhesive strength when bonding a digitally printed plastic film to another film; a laminate film that exhibits such performance; and a food packaging material that uses the laminate film. A 2-component curable polyurethane laminate adhesive composition is used, the composition being characterized by containing a polyol (A) and a polyisocyanate (B) as essential components and characterized in that the number of moles of aromatic ring components is 1.0-2.3 mmol/g relative to the total mass of the polyol (A) and the polyurethane (B).
