摘要

PROBLEM TO BE SOLVED: To provide copper particle-containing ink which prevents viscosity from increasing even when copper particles have high concentration, and has a large amount of copper particles coated by one coating.SOLUTION: Copper particle-containing ink contains a solvent and copper particles, where the copper particles are resin-coated copper particles having a resin thereon. A volume average particle size of the copper particles is 23 nm or more and 60 nm or less, viscosity at 25°C is 9.2 mPa s or more and 10.5 mPa s or less, and the resin is a resin having a copper particle adsorptive functional group, a solvent-affinitive functional group and a solvent-insoluble functional group.SELECTED DRAWING: None
