PURPOSE: To obtain a marking material, excellent in resistances to contamination and weather by laminating and bonding an adhesive agent layer, an intermediate layer, a bonding agent layer and the surface layer of fluorine film on the surface of a separating material layer.
CONSTITUTION: A marking material, consisting of an adhesive agent layer 2, an intermediate layer 3, a bonding agent layer 4 and an surface layer 5 of fluorine film, which are laminated and arranged on a separating material layer 1, is provided with the function of excellent resistances to contamination, weather and chemical product which are possessed by the surface layer or a fluorine film. Polyvinyl fluoride, polyvinylidene fluoride or the like is employed for the fluorine film. Silicone processed paper or the like having separatable property from the adhesive agent layer 2 is employed as the separating material 1 while acrylic resin adhesive agent, prominent in resistances to weather and oil, is employed as the adhesive agent layer 2 usually. A base material such as a plastic film, paper or the like is employed as the intermediate layer 3 while the bonding agent layer 4 bonds the intermediate layer 3 to the surface layer 5 and the performance of the bonding agent is preferably larger than an adhesive property, which breaks the base material of the intermediate layer 3 or the surface layer 5 or the adhesive force of the adhesive agent layer 2.
