Abstract
A moisture-curable hot melt adhesive which is excellent in light resistance and durability against high temperature and high humidity. The moisture-curable hot melt adhesive includes a urethane prepolymer having an isocyanate group at the end and an acrylic based polymer, wherein the urethane prepolymer contains chemical structures derived from a polycarbonate polyol and a non-crystalline polyesterpolyol. The moisture-curable hot melt adhesive can be used to produce an automobile interior material since no deterioration occurs even under sunlight, or under severe high temperature and high humidity conditions in the summer season.
