Organic golden compounds, preparation methods thereof and gold compounds containing them

摘要

The present invention relates to a novel organosulfur compound, a process for its preparation and its use for preparing a formulation for forming a gold ornament on a fire retardant support.;Various organosulfur compounds and their use for forming gold embellishments are known.;Gold compounds according to the present invention can be obtained by dissolving mono (I) dimercaptosuccinic acid and similar structures in the presence of a base, spinning by acidification and, if necessary, repeating the dissolution and precipitation steps. Gold compound according to the invention is characterized in that the gold content of 60 to 90% by weight and the atomic ratio of 0.7 to 4. Preferred gold compounds are water soluble and suitable as constituents of organic / aqueous and wholly aqueous polished and polished gold blends for decorating glass, porcelain and ceramics.
