Patent ID: 8349928

Claim:
A metal particle dispersion structure comprising (B) 0.005 to 100 weight parts of metal particles having an average primary particle size, as determined by electron microscopic observation, in the range of 3 to 1,000 nm dispersed in (A) 100 weight parts of polymer yielded by the polymerization of (a) reactive functional group-containing polymer precursor, wherein the metal particles are metal particles obtained by mixing (b1) at least one organosilicon compound that has at least one silicon-bonded hydrogen atom per molecule and (b2) at least one metal compound having the compositional formula (1) shown below L n M,[L n M] p+ (Q q−) r , or (Q q+ ) r [L n M] p− compositional formula (1): (wherein M is the cation of a metal that has a standard oxidation-reduction potential greater than 0.00 V and is selected from the group consisting of copper (Cu), silver (Ag), gold (Au), and platinum (Pt), L is an organic ligand, Q is a counter ion, n is the number of organic ligands (L) coordinated per metal atom, and p, q, and r are numbers that satisfy the relationship p=q×r.) to uniformity in (b3) cyclic or chain dimethylpolysiloxane that has a viscosity at 25° C. of no greater than 1000 mPa·s or at least one organic solvent.
