PROBLEM TO BE SOLVED: To provide a moisture-curable hot-melt adhesive which has excellent adhesiveness (initial adhesiveness and post-curing adhesiveness), light fastness (light resistant adhesiveness, yellow discoloration resistance, color fading resistance, and the like), and hardenability (heat resistance).SOLUTION: Provided is a moisture-curable hot melt adhesive comprising an alicyclic urethane prepolymer having isocyanate groups at terminals, where the alicyclic urethane prepolymer comprises a chemical structure derived from a polycarbonate polyol and at least one of the terminal isocyanate groups is bonded to a chemical structure derived from an aromatic ring. The adhesive has excellent adhesiveness, light fastness (light resistant adhesiveness, yellow discoloration resistance, color fading resistance, and the like), and hardenability (heat resistance). |
