Film mirror, production process of same and reflection device for solar power generation comprising same

摘要

There are disclosed a film mirror, which can be prevented from decrease in specular reflectance when a silver layer that serves as a reflective layer is deteriorated, is lightweight and flexible, can be produced at low cost, can have an enlarged surface area, can be produced on a large scale, exhibits excellent light stability and weather resistance, and exhibits good specular reflectance to solar light; a process for producing the film mirror; and a reflection device for solar power generation, which is equipped with such a film mirror. The film mirror comprises at least an adhesive layer, a silver reflection layer and an upper adjacent layer as constituent layers provided on the resin substrate sequentially in this order, in which at least the upper adjacent layer contains a binder and a corrosion inhibitor for silver.

主权项

1. A film mirror comprising at least an adhesive layer, a silver reflection layer and an upper adjacent layer as constituent layers provided on a resin substrate sequentially in this order,
wherein at least the upper adjacent layer contains a binder and a corrosion inhibitor for silver, wherein the corrosion inhibitor is a corrosion inhibitor which is adsorptive to silver, wherein the silver reflection layer reflects solar light including visible light, and wherein the mirror has a specular reflectance of visible light of 93% or more.
