Zusammenfassung:	The present invention relates to a method for producing a semi-IPN composite, the method including polymerizing a hydrophilic monofunctional acrylate (b1) and a polyfunctional acrylate (b2) in a solution of a polyurethane (A) prepared using an aromatic polyisocyanate as a raw material. The present invention also relates to a method for producing a moisture-permeable film that is obtained by drying the semi-IPN composite obtained by the above production method. One object of the present invention is to provide a method for producing a semi-IPN composite excellent in moisture permeability, water-swelling resistance, and stain resistance. The semi-INP composite obtained by the production method of the present invention is excellent in moisture permeability, water-swelling resistance, and stain resistance. Therefore, the semi-IPN composite can be preferably used for moisture-permeable waterproof fabrics for clothing, medical, and sanitary use and for skin and topcoat layers of synthetic leathers.
