CONDUCTIVE-PATTERN FORMING METHOD AND COMPOSITION FOR FORMING CONDUCTIVE PATTERN BY PHOTO IRRADIATION OR MICROWAVE HEATING

摘要

Provided are a conductive pattern forming method and a composition for forming a conductive pattern by photo irradiation or microwave heating, capable of increasing the conductivity of the conductive pattern. A conductive pattern is formed by preparing a composition for forming a conductive pattern comprising, copper particles each having a copper oxide thin film on the entirety or a part of the surface thereof, copper oxide particles, a reducing agent such as a polyhydric alcohol, a carboxylic acid, or a polyalkylene glycol, and a binder resin; forming a printed pattern having any selected shape on a substrate using this composition for forming a conductive pattern; and subjecting the printed pattern to photo irradiation or microwave heating to generate a sintered body of copper.
