Un adhesivo de fusión en caliente curable por humedad que comprende: un prepolímero de uretano que tiene un grupo isocianato en el extremo, y un polímero de base acrílica, en el que el prepolímero de uretano contiene estructuras químicas derivadas de un policarbonato poliol y un poliesterpoliol no cristalino, en el que el poliesterpoliol no cristalino es un poliesterpoliol que no tiene punto de fusión.

    An object of the present invention is to provide a moisture-curable hot melt adhesive which is excellent in light resistance and durability against high temperature and high humidity. A moisture-curable hot melt adhesive including 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, is excellent in light resistance and durability against high temperature and high humidity. The moisture-curable hot melt adhesive can be preferably used so as 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.
