Abstract
A method of electroplating non-conductive plastic moldings, the method comprising the steps of: applying a catalyst useful for electroless plating to non-conductive plastic moldings using a colloidal solution containing a precious metal compound and a stannous compound; forming an electrically conductive coating on the surface of the moldings using an electroless copper plating solution containing a copper compound, a saccharide having a reducing property, a complexing agent and an alkali metal hydroxide; and electroplating the coated moldings. According to the method, an electroplated coating excellent in appearance and properties can be formed on non-conductive plastic moldings by a simple procedure.
