CHARGED POWDER FOR FORMING CONDUCTOR PATTERN, METHOD FOR PRODUCING SAME, AND METHOD FOR MANUFACTURING MULTILAYER CERAMIC ELECTRONIC COMPONENT USING SAME

Document Type and Number:

WIPO Patent Application WO/2010/106969

Kind Code:

A1

Abstract:

Disclosed is a charged powder for forming a conductor pattern, which is used for forming a dense conductor layer having low resistance. Also disclosed are a method for producing the charged powder for forming a conductor pattern, and a method for manufacturing a multilayer ceramic electronic component using the charged powder for forming a conductor pattern. Specifically disclosed is a charged powder for forming a conductor pattern, which is used when a conductor pattern is printed on a print-receiving material. The charged powder for forming a conductor pattern is configured of resin particles (3) each of which is formed from a first thermoplastic resin (3a) in which conductive metal particles (1) are dispersed, and a coating resin layer (4) which covers each resin particle (3) and is formed from a second thermoplastic resin (4a) that has a softening point lower than that of the first thermoplastic resin (3a) constituting the resin particles. The difference between the softening point of the first thermoplastic resin and the softening point of the second thermoplastic resin is not less than 20˚C. Ultrafine thermoplastic resin particles having a diameter of 50-500 nm are used for the coating resin layer. A silica coating layer (5) which is configured of silica particles is provided on the surface of the coating resin layer. Each resin particle is formed to contain ceramic particles (2) or glass particles.
