摘要

PROBLEM TO BE SOLVED: To provide a copper fine particle dispersion containing a copper fine particle having a fine particle diameter and excellent in sintering property at a low temperature.;SOLUTION: A method for preparing a copper fine particle dispersion includes the steps of: adding an aliphatic monocarboxylic acid as a reducing agent and as a protecting agent, and a copper compound to a solvent to disperse the copper compound in the solvent in a solid state; and reducing the copper compound dispersed in the solvent to form a copper fine particle with a surface covered with the aliphatic monocarboxylic acid, thereby preparing the copper fine particle dispersion in which the copper fine particle is dispersed in the solvent.;COPYRIGHT: (C)2013,JPO&INPIT
