NOVELTY - A silver compound is mixed with amines that include an aliphatic monoamine (A), which is composed of amino group and 6C or more aliphatic hydrocarbon group, and an aliphatic monoamine (B), which is composed of amino group and 5C or less aliphatic hydrocarbon group, and/or an aliphatic diamine (C), which is composed of amino groups and 8C or less aliphatic hydrocarbon group, so that complex compound containing silver compound is produced. The complex compound is heated and thermally decomposed, to form silver nanoparticles. The silver nanoparticles are dispersed into solvent.    USE - Production of dispersion liquid containing silver nanoparticles used as ink for inkjet printing for electronic device (all claimed). Uses include but are not limited to electromagnetic wave control material, circuit board, antenna, liquid crystal display, organic electroluminescent display, field emission display, solar cell, LED element, organic transistor, capacitor, electronic paper, etc.    ADVANTAGE - The method enables efficient production of dispersion liquid containing silver nanoparticles having excellent stability and electrical conductivity by means of firing at low temperatures. The dispersion liquid containing silver nanoparticles provides silver baking coating film having excellent surface smoothness.    DETAILED DESCRIPTION - A silver compound is mixed with amines that include an aliphatic monoamine (A), which is composed of one amino group and 6C or more aliphatic hydrocarbon group, and an aliphatic monoamine (B), which is composed of one amino group and 5C or less aliphatic hydrocarbon group, and/or an aliphatic diamine (C), which is composed of two amino groups and 8C or less aliphatic hydrocarbon group, so that a complex compound containing the silver compound and the amines is produced. The complex compound is heated and thermally decomposed, to form silver nanoparticles. The silver nanoparticles are dispersed into a solvent that contains an 50-90 wt.% alcohol-based solvent and 10-50 wt.% aliphatic hydrocarbon-based solvent. An INDEPENDENT CLAIM is included for electronic device.
