To impart a antistatic performance to a transparent thermoplastic resin plate so that dirts hardly stick thereto without cleaning with antistatic treatment spray by using the transparent thermoplastic resin plate with one face or both faces coated with surface layers containing a photo-semiconductors for a vending machine front face plate.
A transparent thermoplastic resin plate 1 to 5 mm thick, for example, an acrylic resin plate is used for a front face plate. Metal oxide, such as titanium oxide, tin oxide, zinc oxide, iron trioxide, or bismuth trioxide is cited as a photo-semiconductor coating the surface of the resin plate. The surface layer is formed 0.1 to 100 μm thick by applying a mixture of, for example, anatase titanium oxide and silicone resin to one face or both faces of the resin plate and by heat treating. Thereby, the surface resistivity of the front face plate becomes low so as to obtain excellent antistatic performance, and dirts hardly stick thereto.
