On September 21, 2006, Saijo, Shingo; Yamato, Shigeru; Matsunami, Takashi; Hashimoto, Morihito published a patent.Reference of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride The title of the patent was Method for adjusting plating bath by decomposing organic component without giving adverse effect to plating ability. And the patent contained the following:
Peroxo mono-sulfate is added to the plating bath to oxidation-decompose organic compounds in the plating bath. The plating bath is halogen-containing electroplating bath or electroless plating bath. Optionally, the plating bath is a CuSO4 plating bath. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Reference of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
