Abstract

Official abstract text for this publication.

The silver-coated silicone rubber particles according to the present invention are each formed by providing a first coating layer comprising silicon or a silicon compound on the surface of a silicone rubber particle and further providing a second coating layer comprising silver on the surface of the first coating layer. In a conductive paste containing the silver-coated silicone rubber particles, the silver-coated silicone rubber particles are dispersed evenly.

First claim

Opening claim text (preview).

The invention claimed is: 1. Silver-coated silicone rubber particles comprising: a first coating layer made of either one of silica, silicon, or silicate glass provided on a surface of the silicone rubber particles; and a second coating layer made of silver provided on a surface of the first coating layer. 2. A conductive paste comprising the silver-coated silicone rubber particles according to claim 1 . 3. A method of producing a conductive film using the conductive paste according to claim 2 . 4. The silver-coated silicone rubber particles according to claim 1 , wherein the silica is formed from ethyl ortho silicate, or by adhering silica particles on a surface of the silicone rubber particles. 5. A conductive paste comprising the silver-coated silicone rubber particles according to claim 4 . 6. A method of producing a conductive film using the conductive paste according to claim 5 . 7. A method of producing a conductive film using the conductive paste according to claim 5 . 8. The silver-coated silicone rubber particles according to claim 1 , wherein the silicon is silicon particles adhered to a surface of the silicone rubber particles. 9. A conductive paste comprising the silver-coated silicone rubber particles according to claim 8 . 10. The silver-coated silicone rubber particles according to claim 1 , wherein the silicate glass is formed from ethyl orthosilicate, or by adhering silicate glass particles on a surface of the silicone rubber particles. 11. A conductive paste comprising the silver-coated silicone rubber particles according to claim 10 . 12. A method of producing a conductive film using the conductive paste according to claim 11 .
