METHOD FOR MANUFACTURING SILVER NANOPARTICLE-CONTAINING INK, AND SILVER NANOPARTICLE-CONTAINING INK

摘要

The present invention provides silver nanoparticle-containing ink that develops excellent conductivity by low-temperature calcining and has silver nano-particles stably and well dispersed in a dispersion solvent, and a method for producing the silver nanoparticle-containing ink. A method for producing silver nanoparticle-containing ink, comprising: mixing a silver compound with amines comprising an aliphatic hydrocarbon monoamine (A) comprising an aliphatic hydrocarbon group and one amino group, said aliphatic hydrocarbon group having 6 or more carbon atoms in total; and further comprising at least one of: an aliphatic hydrocarbon monoamine (B) comprising an aliphatic hydrocarbon group and one amino group, said aliphatic hydrocarbon group having 5 or less carbon atoms in total; and an aliphatic hydrocarbon diamine (C) comprising an aliphatic hydrocarbon group and two amino groups, said aliphatic hydrocarbon group having 8 or less carbon atoms in total; to form a complex compound comprising the silver compound and the amines; thermally decomposing the complex compound by heating to form silver nano-particles; and dispersing the silver nano-particles in a dispersion solvent containing an alicyclic hydrocarbon.
