Document Type and Number:
WIPO Patent Application WO/2023/017747
Kind Code:
A1
Abstract:
An electroconductive ink is provided in which metal nanoparticles are inhibited from aggregating. The electroconductive ink comprises surface-modified metal nanoparticles (A) coated with a protectant comprising one or more amines, a wetting dispersant (B), and a dispersing solvent (C). The wetting dispersant (B) preferably has an amine value of 3-145 mgKOH/g and an acid value of 4-185 mgKOH/g. The amines in the surface-modified metal nanoparticles (A) preferably comprise: an aliphatic monoamine (1) having six or more carbon atoms in total; and an aliphatic monoamine (2) having five or more carbon atoms in total and/or an aliphatic diamine (3) having eight or less carbon atoms in total.
