Abstract (en)
[origin: EP3363928A1] Provided is an electroless platinum plating solution that can exhibit solution stability without the use of heavy metal ions or thiol compounds and can prevent the generation of ammonia gas. The electroless platinum plating solution is characterized by comprising a water-soluble platinum compound, and one or more reducing agents selected from the group consisting of formalin, glucose, formic acid and formates. The water-soluble platinum compound is preferably one or more water-soluble platinum compounds selected from the group consisting of platinous chloride (II), hydrogen tetrachloroplatinate (II), tetrachloroplatinate (II), platinic chloride (IV), hydrogen hexachloroplatinate (IV), hexachloroplatinate (IV), hydrogen hexahydroxoplatinate (IV), hexahydroxoplatinate (IV) and dichlorotetraammineplatinum (II). The electroless platinum plating solution preferably comprises an organic acid.
