Abstract
The utility model relates to a laminated film for a touch screen. The laminated film comprises a hard coating layer, a composite base material, a SiOx layer, a SiO2 layer and an ITO layer which are sequentially arranged in a stacking manner, wherein x is in the range from 1.0 to 1.9. The SiOx layer is added between the PET (Polyethylene Terephthalate) base material and the SiO2 layer to serve as a transition layer; and as certain Si-dangling bonds exist in the SiOx layer, the Si-dangling bonds can form C-Si or C-O-Si covalent bonds with C-H or C-OH bonds on the surface of the composite base material, thereby the adhesive force of the SiO2 layer and the ITO layer on the composite base material is enhanced, the requirement for degassing of the composite base material is greatly reduced, the time of degassing treatment is shortened, and the production efficiency is improved. Simultaneously, as the SiOx layer and the SiO2 layer have covering effects on the base material, the influence of water in the composite base material on an ITO coating is avoided, and the stability of an ITO resistor is ensured.
