Filed: 2003-04-22
Abstract: <P>PROBLEM TO BE SOLVED: To form an excellent circuit pattern on an insulating inorganic substrate by an electrophotography method by coating the surface of conductive powder with resin.  <P>SOLUTION: While agitating a mixture containing the conductive powder, a non-water-soluble resin which can be self water dispersible by neutralization and an organic solvent under the presence of a neutralizer, phase inversion emulsification is performed with an aqueous medium so that the maximum viscosity of the mixture at the time of agitation during the phase inversion emulsification is 2 Pas or higher.
