(57) [Summary] Metal (particularly noble metal) supported on resin particle surface Metal particle-supported resin particles capable of efficiently exhibiting the activity of the resin and a method for producing the same. An emulsion-type resin particle having an average particle size of 10 nm to 100 μm, gold and silver having an average particle size of 1 nm to 1 μm, By adding a reducing agent to a solvent containing copper, platinum and other metal ions and a dispersant, and forming a metal colloid from the metal ions, a plurality of metal fine particles are supported on the resin particle surface, and the metal fine particle-supporting resin is formed. Produce particles. |
