Title:
METHOD FOR FORMING METAL COATING FILM, AND ELECTRICALLY CONDUCTIVE PARTICLE
Document Type and Number:
WIPO Patent Application WO/2010/035708
Kind Code:
A1
Abstract:
Disclosed is a method for forming a metal coating film, in which the metal coating film is formed on the surface of a non-electrically-conductive particle by electroless plating. In the method, the electroless plating is carried out after the pretreatment for attaching a metal core to the non-electrically-conductive particle and can form a metal coating film comprising silver in the presence of a hydrophilic polymer having a pyrrolidone group. Also disclosed is an electrically conductive particle which is imparted with electrical conductivity by forming a metal coating film on the whole surface of a non-electrically-conductive particle. The metal coating film comprises a coating film composed of only silver.
