能となったりすることが多々ある。[Prior art/problem to be solved by the invention] Conventionally, polyolefin resin films or polyvinyl chloride (soft resin films with printing applied to them) have been used to protect the surfaces of plate-like objects such as metal plates as described above. A surface protection adhesive film using a base material is known.This film poses no particular problem when used solely for the purpose of storing or transporting a plate-like object, but it may cause surface protection on a plate-like object. If a multi-step drawing process is performed after temporarily attaching a protective film,
There are many cases where the surface protection film breaks or lifts up from the plate-like object, causing damage to the plate-like object during the next process, or making the work impossible.

域は表面保護機能に大きく寄与する。Therefore, in the above applications, a surface protection adhesive film using a non-printed polyvinyl chloride resin is generally used as the base film. This is because the strength (yield point strength), tensile strength, etc. of polyvinyl chloride resin films are superior to polyolefin resins.4 In this way, in surface protection adhesive films, the material area of the base film is used for surface protection. Contributes significantly to functionality.

どの重大な問題が生起する。However, even when the physical properties of the base film are combined, when printing on the base film, when using the ink conventionally used for surface protection adhesive films for plate-shaped objects, the strength of the ink film is is more than an order of magnitude larger than that of the base film, so when applying a surface protection adhesive film using a printed base film and performing a multi-step drawing process, there may be cuts, lifting, dents, etc. Serious problems such as

Furthermore, it is an object of the present invention to provide a surface protection adhesive film that is less likely to cause dents or the like on plate-shaped objects.

いう新知見を得た。The present inventor has conducted various studies in order to solve the above-mentioned problems, and has found that in a surface protection adhesive film using the above-mentioned printing film as a base material, the film strength of the printing ink (i.e., the strength of the ink) (Young's modulus in a dry state) does not greatly exceed that of the base film, specifically, the Young's modulus of the base film is 1
The above problems can be solved by using an ink that forms a film strength having a Young's modulus not exceeding 20%, and for this purpose, the initial modulus value (Young's modulus) of the physical properties of the ink is usually 50 kg. A new finding has been obtained that it is suitable to use an ink that forms a film strength of 0.2 mm" or less.

ける打痕等の発生が少ないという効果が得られる。Therefore, even when the surface protection adhesive film is applied to a plate-shaped object and the plate-shaped object is subjected to multi-step drawing processing, there is very little chance of the film breaking or lifting up, and furthermore, the occurrence of dents etc. on the plate-shaped object is minimized. You can get the effect of less.
