Highly weatherable, moisture-curable, one-component polyurethane composition which is curable with moisture in the air is provided at lower costs. The composition contains a main component which will form a polyurethane resin upon curing, and additives. The additives are one or more photocurable materials selected from the group consisting of unsaturated acrylic compounds, polyvinyl cinnamate, and azide-containing compounds; and a hindered amine photostabilizer. The additives may preferably further contain a thixotropy endowing agent comprising a blocked amine compound forming primary or secondary amino group with moisture, or a polyurea compound.
