titleOfInvention | Composition for blackening treatment of copper metal or silver metal |
abstract | The present invention relates to a copper circuit of a printed wiring board, a circuit formed of a silver paste, and other various copper, copper alloys, silver, silver alloys, and other articles containing copper metals or silver metals. It is an object of the present invention to provide a novel blackening treatment composition that can be sufficiently blackened without impairing the smoothness of the base metal. The present invention provides (i) at least one water-soluble metal compound selected from the group consisting of a water-soluble palladium compound, a water-soluble ruthenium compound, and a water-soluble silver compound, (Ii) at least one halide selected from the group consisting of hydrohalic acids, metal halides and ammonium halides; and (iii) a group consisting of alkylenediamine, polyalkylenepolyamine, polyamide polyamine and polyamide polyamine cross-linked product. A composition for blackening treatment of a copper-based metal or a silver-based metal comprising an aqueous solution containing at least one nitrogen atom-containing compound selected from 1 is provided. |
