(57) [Abstract] [Purpose] Ultrafine metal particle dispersion composition excellent in transparency, stability and environmental characteristics as a non-linear optical material useful as one of optical wavelength cut filter and optoelectronic device material, and method for producing the same. I will provide a. [Structure] Ultrafine metal particles stabilized by a polymer having a pyrrolidone group, and further another polymer compatible with the metal coexist in an organic solvent, and the solvent is removed from this solution to obtain transparency, dispersibility, and An ultrafine metal particle-dispersed polymer composition having excellent environmental characteristics is obtained. |
