| abstract |
The present invention provides an adsorbent substance that can exhibit adsorption performance in the state of a molded product obtained by blending a masterbatch with a resin without exhibiting adsorption performance in the state of the masterbatch. It is providing the masterbatch used for formation of a metal ultrafine particle, and its manufacturing method. A thermoplastic resin contains an organic acid metal salt, and the metal of the organic acid metal salt is Cu, Ag, Au, In, Pd, Pt, Fe, Ni, Co, Zn, Nb. , Sn, Ru, and Rh, and is used for forming ultrafine metal particles.
