    • In forming a thin film of silver mirror on a surface of an object to be coated, a silver mirror reaction-treating solution including three solutions: an ammoniacal silver salt aqueous solution (I), an aqueous solution of caustic soda (IIa) and an aqueous solution of a carbohydrate-based reducing agent (IIb) such as glucose (fructose) are used. Immediately after the caustic soda aqueous solution (IIa) and the reducing agent aqueous solution (IIb) are mixed, the resulting mixed liquid and the ammoniacal silver salt aqueous solution (I) are independently and simultaneously sprayed onto the object. Alternatively, the mixed liquid (II) and the ammoniacal silver salt aqueous solution (I) are mixed together immediately upstream of a spraying nozzle, and the mixed liquid (III) is sprayed onto the object. Thereby, a thin film of silver mirror is formed in a thickness of around 0.01 to 0.03 μm, for example, through depositing silver by a silver mirror reaction.
    • 在形成被涂物的表面上的银镜的薄膜时,可以使用含有三种溶液的银镜反应处理溶液:氨水银溶液(I),苛性钠水溶液(IIa)和 使用碳水化合物系还原剂(IIb)如葡萄糖(果糖)的水溶液。 在苛性钠水溶液(IIa)和还原剂水溶液(IIb)混合之后,将所得到的混合液体和氨水银盐水溶液(I)独立地同时喷雾到物体上。 或者,将混合液(II)和氨银盐水溶液(I)紧密地混合在喷雾喷嘴的上游,将混合液(III)喷雾到物体上。 由此,例如通过银镜反应沉积银,形成厚度为0.01〜0.03μm左右的银镜的薄膜。
