CAPSULATED PARTICLE FOR ELECTROSTATIC CHARGE IMAGE DEVELOPING AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide capsulated particles for electrostatic charge image developing for forming a high definition and low resistance electrically conductive wiring pattern on an insulating inorganic substrate by an electrostatic printing method. SOLUTION: In the capsulated particles for an electrostatic charge image developing having fine metal particles and insulating resin films which encapsulate the particles, the volume average particle diameter of the capsulated particles is 0.5-15μm, the weight proportion of the insulating resin to the capsulated particles is <=20% and the capsulated particles have a particle size distribution of certain sharpness. A method for forming an electrically conductive wiring pattern is provided by which an electrostatic charge image developer is composed using the capsulated particles and a wiring pattern is formed on an insulating inorganic substrate by an electrostatic printing method and sintered.
