PROBLEM TO BE SOLVED: To obtain an ecofriendly curable composition that has low viscosity, improved workability, excellent storage stability and no foaming in a cured material in spite of being an isocyanate group-containing urethane prepolymer-containing curable composition using no environmental loading substance such as an organic solvent. SOLUTION: The ecofriendly curable composition comprises an isocyanate group-containing urethane prepolymer (A), a filler (B) and/or a thixotropy-imparting agent (C) and a reaction product (E) between an inorganic reaction type dehydrating agent (D) and water contained in the filler and/or the thixotropy-imparting agent and, if necessary, one or more kinds of additives selected from the group consisting of an inorganic reaction type dehydrating agent (D), a storage stabilizer, weathering stabilizer, adhesiveness imparting agent, plasticizer, colorant and curing promotion catalyst and contains substantially no organic solvent. The composition has low viscosity, excellent workability and storage stability and no foam in a cured material even without using an organic solvent. COPYRIGHT: (C)2005,JPO&NCIPI
