Title:
DISPERSION INK OF ULTRAFINE PARTICLE OF METAL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2010196087
Kind Code:
A
Abstract:

To provide a dispersion ink of ultrafine particles of a metal, in which copper nanoparticles are filled at high concentration in a phenol resin.

This production method includes adding copper hydroxide into an alcohol solution in which approximately 0.5-15 mass% of the phenol resin has been dispersed, stirring the mixed liquid, and adding a reducing agent such as hydrazine into the mixed liquid to precipitate the copper nanoparticles. The precipitated copper nanoparticles have the average particle diameter of 100 nm or less, are uniformly dispersed at high concentration in the precipitate in a state of having the phenol resin adsorbed on the surface. The paint film can be used as a material of an electroconductive ink and the like, because of showing high electroconductivity.
