SILVER PASTE, AND CONDUCTIVE MOLDED ARTICLE OBTAINED USING SAME

A problem is to provide a silver paste which can produce, without variation in resistivity value, a conductive silver coating film exhibiting resistivity substantially equivalent to the resistance value of bulk silver in low-temperature sintering. The problem is solved by providing a silver paste in...

Beschreibung
Zusammenfassung:	A problem is to provide a silver paste which can produce, without variation in resistivity value, a conductive silver coating film exhibiting resistivity substantially equivalent to the resistance value of bulk silver in low-temperature sintering. The problem is solved by providing a silver paste including a silver nanoparticle aqueous dispersion prepared by using a compound having a polyethyleneimine skeleton as a protective agent, a compound having a functional group reactable with nitrogen atoms in the polyethyleneimine, and at least one compound selected from the group consisting of a compound having an amine functional group and a compound having an amide functional group.
