PROBLEM TO BE SOLVED: To provide a silicone water repellent eliminating insufficiency of durability, generation, etc., of hydrogen gas which are disadvantages of conventional silicone water repellents and having a soft touch feeling and to provide a method for imparting water repellency and an inexpensive method for producing a water repellency imparting material. SOLUTION: Water-repellent performances having excellent durability can be imparted to various materials at a low cost by treating an amino-modified silicone in a state of an oil or a state of an emulsion prepared by emulsification thereof using a surfactant with a polyfunctional isocyanate, a polyfunctional blocked isocyanate and a water-dispersed polyfunctional isocyanate in combination.
