Title:
METAL NANOPARTICLE AQUEOUS DISPERSION
Document Type and Number:
WIPO Patent Application WO/2017/183624
Kind Code:
A1
Abstract:
The present invention provides a metal nanoparticle aqueous dispersion which is characterized by containing: a composite body of a metal nanoparticle (X) and an organic compound (Y); and one or more compounds (Z) selected from the group consisting of lactic acid, glycolic acid, malonic acid, succinic acid, fumaric acid, maleic acid, malic acid, tartaric acid, oxalic acid, citric acid and alkali metal salts of these carboxylic acids. This metal nanoparticle aqueous dispersion is able to be suppressed in deterioration over time and in suspension, aggregation and precipitation due to inclusion of a small amount of impurities. In addition, this metal nanoparticle aqueous dispersion is free from the occurrence of characteristics deterioration due to corrosion and appearance defects of a base due to coloring even if a metal having a higher ionization tendency than the metal that constitutes the metal nanoparticles is present on the base surface to which the metal nanoparticles are applied, and is thus able to be stabilized.
