In particular, the probability of occurrence is high in export cars that have a long transportation and storage time, and oil-based or water-based wax-based coating film protective agents have been conventionally used. However, these coating film protective agents are insufficient in preventing the coating film from being contaminated by adhesion of iron powder or the like, bird droppings or acid rain, and the adverse effect of the permeation of the coating film by the wax itself or 3
If it is left outdoors for a long time of more than one month, peeling becomes difficult,
Alternatively, there are problems such as pollution and treatment costs due to wastewater generated during removal.

A method using a film disclosed in Japanese Patent No. 300281 and Japanese Patent Application Laid-Open No. 3-221169 has been proposed. However, the cost is higher than that of a conventional wax-based coating film protective agent, and the adhesive strength when left outdoors for a long time. There is a problem that the temperature rises and the peelability deteriorates. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coating film protective film, which has good workability and does not stain the coating film, at low cost.

である。BEST MODE FOR CARRYING OUT THE INVENTION Here, a white plastic film means polyethylene or polypropylene and α-olefins such as ethylene, propylene and butene, and a copolymer of monomers such as vinyl acetate and methyl methacrylate, alone or as a mixture, or chloride. Examples thereof include vinyl and polyester. Antioxidants, ultraviolet absorbers, lubricants, plasticizers and the like may be added to these films for the purpose of improving weather resistance, heat resistance, processability and workability. Either precipitated calcium carbonate or ground calcium carbonate may be used as the calcium carbonate to be added in order to improve the heat resistance and mechanical strength of the plastic film, or to improve the peelability from the coating film and reduce the cost. The added amount is 10 wt% or more, preferably 15 wt% or more. If it is less than 10 wt%, the above effect cannot be obtained. Next, the coloring of the plastic film is carried out by adding a pigment or printing on the back surface of the support, which is usually performed. The pigments and inks added here are required to have weather resistance for the purpose of the present invention, and inorganic ones are preferably used. In order to improve the weather resistance of the pressure-sensitive adhesive and the film, it is necessary that the degree of coloring be 5% or less, preferably 1% or less in the range of 190 to 370 nm of ultraviolet ray transmission.

ｔ％のものである。The color of the plastic film must be white of N8 or more in the Munsell color system. Black, which uses carbon black and the like, has excellent concealing properties and light-shielding properties, and the amount of UV light transmitted can be reduced to 10% or less by adding a small amount, but the heat increase due to absorption is large, and direct sunlight in summer brings the temperature to 80 ° C.
Because of the above high temperature, problems such as thermal deformation of the coating film easily occur. On the other hand, in the case of a Munsell color system having a white color of N8 or more, the temperature rise is small at 60 to 70 ° C, which is preferable. However, in the case of white, since the light-shielding property of the pigment or the like is small, the weather resistance of the support itself is insufficient, and it is necessary to add a weather resistance improver. Here, as the weather resistance improver, amine-based, quinoline-based, hydroquinone-based, phenol-based, phosphite-based antioxidants, antioxidants, salicylic acid derivatives, benzophenone-based, benzotriazole-based, hindered amine-based, etc. The ultraviolet absorbers, light stabilizers, etc. are particularly preferable, and hindered amine-based ones are particularly preferable since they are excellent in compatibility and weather resistance improving effect. The addition amount is preferably 0.1 to 10 parts by weight. If it is less than 0.1 part by weight, no effect is obtained, and if it exceeds 10 parts by weight, there is an adverse effect due to migration of the additive to the pressure-sensitive adhesive. On the other hand, in the olefin film used as a support for the adhesive film, the propylene structure ethylene structure exists in the state of a mixture or copolymer of homopolymers or a mixture of homopolymers and copolymers, and the content of ethylene structure is 5 wt% or less. 40w

The pigments and inks added here are required to have weather resistance for the purpose of the present invention, and inorganic ones are preferably used.

がある。It is necessary that the support is white with a Munsell color system of N8 or more. A black color using carbon black or the like is excellent in hiding and light-shielding properties, and a small amount of addition can reduce the amount of ultraviolet rays transmitted to 10% or less, but the heat increase due to absorption is large, and the temperature may rise above 80 ° C due to direct sunlight in summer. Since the temperature is high, problems such as thermal deformation easily occur in a coating film having a low Tg. On the other hand, in the case of a Munsell color system having a white color of N8 or more, the temperature rise is small at 60 to 70 ° C., which is preferable. However, in the case of white, since the light-shielding property of the pigment or the like is small, the weather resistance of the support itself is insufficient, and it is necessary to add a weather resistance improver. Here, the weather resistance improver is amine-based, quinoline-based, hydroquinone-based, phenol-based, phosphite-based antioxidants, antioxidants, or salicylic acid derivatives,
Examples thereof include benzophenone-based, benzotriazole-based, hindered amine-based ultraviolet absorbers, light stabilizers, and the like. In particular, hindered amine-based ultraviolet absorbers are preferable because of their excellent compatibility and weather resistance improving effects. The addition amount is preferably 0.1 to 10 parts by weight. If less than 0.1 part by weight, no effect is obtained and 10
If it exceeds the amount by weight, there is an adverse effect due to the transfer of the additive to the adhesive.

Examples thereof include copolymerizing a monomer having a crosslinkable functional group such as a carboxylic acid group and a hydroxyl group, and a chlorinated product. The number average molecular weight of the main component must be 80,000 or more and 800,000 or less. When it is 80,000 or less, the cohesive force and weather resistance of the pressure-sensitive adhesive are insufficient, and when it is 800,000 or more, the adhesive force in the low temperature region is insufficient.
The method of measuring the molecular weight includes high performance liquid chromatography, viscosity method, ultracentrifugation method, light scattering method, membrane osmotic pressure method, boiling point elevation method, etc., but high performance liquid chromatography method is simple and as a general method. Widely used.

る。It is needless to say that the pressure-sensitive adhesive used in the present invention may contain, in addition to the above main components, commonly-used compounding agents such as a softening agent and a tackifier. In particular, the tackifier has a great effect on improving the adhesive strength of the pressure sensitive adhesive containing polyisobutylene, butyl rubber or polybutene as the main component. Examples of the tackifier include natural resins such as rosin, rosin derivative, terpene resin, terpene phenol resin, dammar, copal and shellac, and petroleum resin such as aliphatic, aromatic and alicyclic resins, alkylphenol resin and modified resin. Phenolic resin such as phenolic resin, xylene resin-based and the like, especially terpene phenolic resin-based ones have good compatibility with polyisobutylene, and also have suitable polarity, so as a tackifier for this application. desirable. The addition amount is from 1 to 20 parts by weight. If it is less than 1 part by weight, the effect of improving the adhesive strength cannot be obtained, and if it exceeds 20 parts by weight, the transfer of the tackifier to the coating film becomes remarkable or the adhesive agent Adhesive residue occurs due to a decrease in cohesive strength of. The plastic film cut into a predetermined shape is placed on an adherend, and the entire periphery of the plastic film is fixed by a tape-shaped adhesive film.
