Abstract
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 for use as a metal salt solution for forming a metallic mirror surface on a receiving surface is shown. The receiving surface is treated with an activating treatment agent containing stannous chloride and at least one precious metal salt of palladium, gold, silver or the like 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.
