    摘要: Provided is a moisture curable polyurethane composition that is a moisture curable polyurethane having an isocyanate group on one end of a molecule thereof. The moisture curable polyurethane composition contains a moisture curable polyurethane (A) and an organic solvent (B). The moisture curable polyurethane (A) is obtainable by reacting a polyisocyanate compound having at least two isocyanate groups in a molecule thereof (A1) with a low-molecular weight polyol compound having at least two hydroxyl groups in a molecule thereof and having a number average molecular weight of 50-300 (A2). Also provided is a laminate including an optical substrate and a polyurethane resin layer comprising the moisture curable polyurethane composition.
