  • Publication number: 20180355191
    Abstract: Provided is an electro-conductive paste suitable to yield a sintered metal fine particulate layer having excellent adhesion to an ITO substrate. Powdery silver oxide is dispersed in a non-polar solvent. An excess amount of formic acid is added to allow the formic acid to react with the powdery silver oxide to thereby convert the powdery silver oxide into powdery silver formate (HCOOAg). A primary amine is allowed to react with the powdery silver formate to provide a primary amine addition salt of the silver formate, and the primary amine addition salt of the silver formate is subjected to a decompositional reduction reaction at a liquid temperature of around 70° C. to generate silver nanoparticles having a coating layer including the primary amine. To the resulting silver nanoparticle dispersion liquid, more than 0 parts by mass and 2.0 parts by mass or less of a titanium compound or manganese compound is added per 100 parts by mass of silver.
