POLYURETHANE RESIN COMPOSITION |
摘要 |
<p>To provide a polyurethane resin composition which exhibits high gas-barrier property and excellent adhesion to various polymers, paper, metals, etc., which can prevent generation of cracks or pinholes in a gas-barrier layer through flexion treatment, and which exhibits excellent content resistance; an adhesive containing the resin composition; and a multi-layer film containing the adhesive. The invention provides a polyurethane resin composition containing an active hydrogen compound (A) formed by adding m-xylylene diisocyanate and/or hexamethylene diisocyanate to a specific compound (C) at a reaction equivalent ratio ([the number of isocyanate groups]/[the number of hydroxyl groups]) of 0.80 to 0.10; and an organic polyisocyanate compound (B) formed by adding a specific compound (D) to m-xylylene diisocyanate and/or hexamethylene diisocyanate at a reaction equivalent ratio ([the number of isocyanate groups]/[the number of hydroxyl groups]) of 2 to 10; an adhesive and a coating material containing the resin composition; and a multi-layer film and a packaging bag containing any of these.</p> |
