SILVER NANOPARTICLE INK

Title:

SILVER NANOPARTICLE INK

Document Type and Number:

Japanese Patent JP2017155220

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide improved, stable conductive inks that meet requirements for pneumatic aerosol printing processes for low-cost electronic device applications.SOLUTION: An ink composition includes: metal nanoparticles; at least one aromatic hydrocarbon solvent compatible with the metal nanoparticles; and at least one aliphatic hydrocarbon solvent compatible with the metal nanoparticles. The ink composition has a metal content greater than about 45 wt.% based upon the total weight of the ink composition, and has a viscosity of about 5 to about 30 centipoise at a temperature of about 20 to about 30°C. In an ink composition, the metal nanoparticles are silver particles. Also provided are a process for preparing the ink composition, and a process for printing with the ink composition comprising pneumatic aerosol printing.SELECTED DRAWING: None
