An antistatic agent containing a cationic and/or amphoteric, water-soluble or water-dispersible and heat-reactive blocked urethane prepolymer as an essential component, said prepolymer having at least one cationic group and/or at least one amphoteric group in its molecule and having isocyanate groups blocked with a thermally dissociable blocking agent. The antistatic agent is applicable to various materials and can give the antistatic property with the water repellency, which can be kept for a long term, to the materials.
