Abstract

929,220. Gold plating solutions. SEL-REX CORPORATION. Feb. 1, 1962 [May 1, 1961], No. 3952/62. Class 41. Gold plating solutions containing silver to give a low carat plate of 14 to 24 K, also contain soluble gold and silver cyanides and a water-soluble titanium compound e.g. amino alcohol titanate. This may be made by treating isopropyl titanate with ethanolamine, adding sorbitol hemihydrate as stabilizing agent, and removing the isopropyl alcohol. Other stabilizers include inositol, sucrose and related unsaturated alcohol and acid derivatives of 3 to 7 C atoms and 3 to 6 hydroxy groups e.g. aconitic acid or sodium salts thereof. The plating solution also preferably includes a soluble selenium compound e.g. selenium diethyl dithio carbamate, or sodium selenite. Specifications 759,181 and 763,010 are referred to.
