摘要： A conductive coated composite body is disclosed which has both good adhesion of a conductive coating film to a base and excellent electrical conductivity of the conductive coating film at the same time even in cases where a glass base or a base having low heat resistance is used; and a method for producing this conductive coated composite body. A conductive coated composite body includes: a base; a resin layer that is formed on at least a part of the base; and a conductive coating film that is formed on at least a part of the resin layer. The conductive coating film is a sintered body of silver fine particles; the main component of the resin layer is a polyurethane resin having an elongation at break of 600% or more; and the polyurethane resin has one of the functional groups represented by —COO—H, —COOR, —COO−NH+R2 and —COO−NH4+.

摘要： Provided are a fine silver particle dispersion which exhibits low temperature sinterability and in which fine silver particles are uniformly dispersed in a variety of solvents (and especially highly polar solvents); fine silver particles that exhibit low temperature sinterability and excellent dispersion stability in a variety of solvents (and especially highly polar solvents); a dispersion obtained using the fine silver particles; and a method for producing same. The fine silver particle dispersion is characterized by containing fine silver particles, a short chain amine having 5 or fewer carbon atoms, and a highly polar solvent and in that the partition coefficient (log P) of the short chain amine is −1.0 to 1.4.
