| titleOfInvention | Composition for blackening copper-based or silver-based metals |
| abstract | The present invention addresses the problem of providing a new composition for blackening that, without compromising the smoothness of copper-based or silver-based metals, allows for sufficient blackening of copper circuits of printed wiring boards, circuits formed by silver paste, and products containing copper-based or silver-based metals, such as other various kinds of copper, copper alloys, silver, and silver alloys. The present invention provides a composition for blackening copper-based or silver-based metals, said composition comprising an aqueous solution containing (i) at least one water-soluble metal compound selected from the group consisting of water-soluble palladium compounds, water-soluble ruthenium compounds, and water-soluble silver compounds; (ii) at least one halide selected from the group consisting of hydrohalic acids, metal halides, and ammonium halides; and (iii) at least one nitrogen atom–containing compound selected from the group consisting of alkylene diamines, polyalkylene polyamines, polyamide polyamines, and cross-linked polyamide polyamines. |
