PROBLEM TO BE SOLVED: To provide a moisture-permeable watertight coated fabric having not only moisture permeability and watertight properties but also excellent tear strength which is impossible in a conventional coated fabric. SOLUTION: The moisture-permeable watertight coated fabric with the excellent tear strength is obtained by forming a nonporous film having <8 g/m<SP>2</SP>weight of the dried resin film comprising a mixed resin of an acrylic resin and a polyurethane resin as the first layer, and a fine porous film having 8-25 g/m<SP>2</SP>weight of a dried resin film consisting essentially of a polyurethane resin as the second layer. The fabric preferably has≥20 kPa water-resistant pressure and≥4,000 g/m<SP>2</SP>/24 hr water vapor permeability. COPYRIGHT: (C)2004,JPO
