<P>PROBLEM TO BE SOLVED: To provide a formulation for a copper particle dispersion comprising dispersed copper particles. <P>SOLUTION: The copper particle dispersion has copper particles, at least one dispersion medium which contains the copper particles, and at least one dispersant for dispersing the copper particles in the dispersion medium. The copper particles have a median particle diameter of greater than or equal to 1 nm and less than 100 nm. The dispersion medium is a polar dispersion medium. The dispersant is a compound having at least one acidic functional group and a molecular weight of 200 to 100,000, or a salt thereof. By this configuration, the dispersant is compatible with the dispersion medium, and, because the surface of the copper particles is covered by dispersant molecules, the copper particles are dispersed in the dispersion medium. <P>COPYRIGHT: (C)2013,JPO&INPIT |
