A metal salt solution for use as a metal salt solution for forming a metallic mirror surface on a receiving surface is shown. The metal salt solution contains about 6.0 g to about 25 g of sodium hydroxide, about 20 g to about 70 g of ammonia and about 2 g to about 20 g of silver nitrate per 1 liter of water. The receiving surface is treated with an activating treatment agent solution containing stannous chloride and at least one precious metal salt of palladium, gold, silver and platinum followed by a concurrent application of the above reacting metal salt solution and reducing agent solution to form a metallic mirror surface on the receiving surface.

1. Field of the Invention
The foregoing and other advantages of this invention will be apparent from the following description of the preferred embodiment of the invention when considered with the illustrations and accompanying drawings, which include the following Figures:
FIG. 1 is a pictorial representation of a receiving surface having a metallic mirror surface formed thereon;
FIG. 2 is a pictorial representation of a receiving surface having a primer coating located between a metallic mirror surface and a receiving surface to enhance adhesion therebetween;
The present invention employs a method for forming a metallic mirror surface that involves adjustment of an underlay that forms the metallic mirror surface, applying an activating treatment and then applying a water-wash treatment to the underlay, followed by a reaction to reacting metal salt and reducing agent to form the metallic mirror surface. An activating treatment, including an activating treatment agent solution, containing stannous chloride and precious metal salts of palladium, gold, silver and the like is sprayed on the substrate, surface or article which is to have a metallic mirror surface formed thereon. The method includes the simultaneous but separate spraying of separate solutions forming the activating reaction treatment agent as well as two separate solutions forming a metal salt solution and reducing agent solution.
Further, this invention discloses and teaches a hydrochloric acid solution which contains contain about 10 cc to about 44 cc of hydrochloric acid, about 1.5 g to about 5 g of stannous chloride and about 0.001 g to about 0.005 g of palladium chloride per 1 liter of water and which is employed as the activating-treatment agent in the method for forming a metallic mirror surface.
Additionally, the method may employ or utilize a metallic mirror reaction treatment agents comprising a metal salt solution containing about 6.0 g to about 25 g of sodium hydroxide, about 20 g to about 70 g of ammonia and about 2 g to about 20 g of silver nitrate per 1 liter of water and a reducing agent solution containing about 1 g to about 4.5 g of tartaric acid, about 10 g to about 50 g of glucose and about 0.05 g to about 3.5 g of formaldehyde.
