PURPOSE: To obtain a pressure-sensitive adhesive film highly resistant to external pollutants such as droppings and acid rain.
CONSTITUTION: This film is composed of a support layer, an adhesive layer formed on one surface of the support layer and a barrier layer formed on the other surface of the support layer. The barrier layer may be formed on each surface of the support layer. It is desirable that the support layer is made of a polyethylene, a polypropylene, a polyethylene/polypropylene mixture or an ethylene/propylene copolymer resin, and that the barrier layer is made of a polyester, a polyimide, a fluororesin, a polyvinyl alcohol, an ethylene/vinyl acetate copolymer, an ethylene vinyl acetate copolymer saponificate, a nylon, a metal or another inorganic substance.
