Provided is a dendritic silver-coated copper powder which is capable of effectively ensuring a contact, while having excellent electrical conductivity by having the surface coated with silver. This dendritic silver-coated copper powder has excellent uniform dispersibility that is necessary for the formation of a paste, and is suppressed in agglomeration. A silver-coated copper powder according to the present invention is obtained by coating the surface of a copper powder 1, which is an assembly of copper particles 2 and has a dendritic form having a plurality of branches, with silver. Each copper particle 2, the surface of which is coated with silver, is an ellipsoid that has a breadth within the range of from 0.2 µm to 0.5 µm and a length within the range of from 0.5 µm to 2.0 µm. The average particle diameter (D50) of the copper powder 1, which is obtained by coating the surface of the assembly of the ellipsoidal copper particles 2 with silver, is from 5.0 µm to 20 µm.

The binder produced according to the invention can be used to produce a wide variety of coating products adhering directly on plastics without chemical or physical pretreatment of any kind. It is possible to produce primers, high-gloss lacquers, metallic lacquers, clearcoat lacquers and special-effect lacquers which can be applied directly to plastics; this is absolutely novel because there is then no need for pretreatment. The binder produced according to the invention can also be used to formulate adhesives which ensure very good adhesive bonding between plastics themselves and also paperboard used in packaging. The invention relates to the binder and to resultant primers, single-coat lacquers and adhesives.
