Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coating material excellent in water repellency, rub fastness and handle, suitable for coating by the reverse roll coating method, and suitable for use in processing leather or textile.SOLUTION: An aqueous dispersion comprises (A) at least one polyurethane, (B) at least one compound of the formula Ia or Ib, and (C) at least one silicone compound having reactive groups. [Rto Rare independent from each other and are A-NCO or A-NH-CO-X; Ais a C2-20 alkylene group; and X is a mono- or polyalkylene oxide group.] 【課題】撥水性、摩擦堅牢性、手触りに優れ、逆ロール被覆法による被覆に好適で皮革や繊維の処理用途に好適な被覆剤の提供。【解決手段】Ａ）少なくとも一種のポリウレタン、（Ｂ）少なくとも一種の式Ｉａ又はＩｂの化合物及び（Ｃ）少なくとも一種の反応性基を有するシリコーン化合物を含む水性分散液。［Ｒ１〜Ｒ３は互いに独立にＡ１−ＮＣＯとＡ１−ＮＨ−ＣＯ−Ｘ；Ａ１はＣ２〜２０のアルキレン基；Ｘはモノ又はポリアルキレンオキシド基］【選択図】なし
