Abstract
Disclosed is a nickel ink comprising a dispersion medium and nickel particles dispersed in the medium and containing a methyldimethoxysilane coupling agent. The dispersion medium comprises a glycol having a boiling point of 300° C. or lower at ambient temperature, an alkoxyethanol having 3 to 10 carbon atoms, and an ether having 2 to 8 carbon atoms. The ink preferably has a surface tension adjusted to 15 to 50 mN/m and a viscosity at 25° C. adjusted to 0.6 to 60 mPa·sec. The ink is preferably used in inkjet printing.
Claims9
An ink consisting of metallic particles, a dispersion medium, and a methyldimethoxysilane coupling agent, wherein said metallic particles consist of nickel particles, the dispersion medium consisting of a glycol having a boiling point of 300° C. or lower at 1 atm, an alkoxyethanol having 3 to 10 carbon atoms, and an ether having 2 to 8 carbon atoms.
A method of producing a conductor film comprising applying an ink to a substrate and firing the resulting coating film at 150 to 950° C. to obtain a conductor film having an average surface roughness Ra of 10 nm or smaller and a maximum surface roughness Rmax of 200 nm or smaller,
- wherein the ink consists of metallic particles, a dispersion medium, and a methyldimethoxysilane coupling agent, wherein said metallic particles consist of nickel particles, the dispersion medium consists of a glycol having a boiling point of 300° C. or lower at 1 atm, an alkoxyethanol having 3 to 10 carbon atoms, and an ether having 2 to 8 carbon atoms.
