Patent attributes
A silver particle dispersion liquid comprising a silver particle powder having an average particle diameter (DTEM) of 50 nm or less, the surface of the particle being covered with an organic protective material, dispersed in a non-polar or small polar liquid organic medium having a boiling point of 60 to 300° C., wherein the organic protective material is an amine compound having one or more unsaturated bonds in one molecule. The silver particle dispersion liquid can be produced by reducing a silver compound in a liquid including one or more alcohol or polyol acting as a reducing agent, wherein the reduction reaction is conducted in the presence of an amine compound having a molecular weight of 100 to 1,000 and having one or more unsaturated bonds in one molecule.
