Abstract
The invention relates to a coating liquid for forming a silver film on a substrate. The coating liquid includes a first ammoniacal aqueous solution containing silver nitrate and a second aqueous solution containing a reducer, a strong alkali, and at least one member selected from the group consisting halides and water-soluble proteins. The first and second aqueous solutions are reacted for forming the silver film on the substrate. The silver film formed from the coating liquid is fine and in texture, is superior in adhesion to the substrate, and enables a precise reflection image.
