する表面保護フィルムに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface protective film. More specifically, the present invention is applied to protect a surface of a metal plate such as a stainless steel plate or an aluminum plate, a painted metal plate or a resin plate, a vinyl chloride laminated steel plate, a glass plate, and the like when transporting, processing, and curing. The present invention relates to a surface protective film having uses such as being applied.

もより一層高度なものが求められる。2. Description of the Related Art The characteristics required for a surface protective film are that the protective film does not float or peel after being attached to an adherend, and the adhesive remains on the adherend when peeled off. It is not. In particular, when the substrate is subjected to severe conditions, such as high temperature or outdoor exposure, between the time of sticking to the adherend and the time of peeling, even higher characteristics are required for the above characteristics.

が挙げられる。[0003] For this reason, as a surface protective film that has been generally used in the past, an acrylic copolymer is crosslinked three-dimensionally with an isocyanate compound or a methylol compound to the extent that the tackiness is not lost, thereby increasing the cohesive force. Examples thereof include those using an adhesive and those using a synthetic rubber, natural rubber, or modified natural rubber mixed with an appropriate amount of a tackifier.

When a conventionally known surface protection film is attached to a surface-roughened vinyl chloride laminated steel sheet whose surface is embossed, the plasticizer bleeds out into the pressure-sensitive adhesive layer, as follows. Problems arise.

て、粘着剤の接着力が低下して表面保護フィルムが被着
体から浮いたり、被着体から表面保護フィルムを剥離す
る際に粘着剤が糸引き現象を呈して被着体に残留する。(1) When the pressure-sensitive adhesive layer is composed of a pressure-sensitive adhesive composition containing an acrylic copolymer as a main component, the pressure-sensitive adhesive composition has good compatibility with a plasticizer such as DOP. Therefore, the plasticizer migrates into the pressure-sensitive adhesive layer, and the cohesive force of the pressure-sensitive adhesive is extremely lost, resulting in a sticky state. Therefore, the adhesive strength of the pressure-sensitive adhesive is reduced and the surface protective film floats from the adherend, or the adhesive exhibits a stringing phenomenon and remains on the adherend when the surface protective film is peeled from the adherend.

However, due to the unsaturated double bonds in the structure of natural rubber and modified natural rubber, ultraviolet rays can cause molecular breakage when exposed outdoors, causing the adhesive to adhere to the adherend when peeling off the surface protection film.

表面保護フィルムを提供することである。[0008] The problem to be solved by the present invention is to solve the above-mentioned problems. In particular, the adhesive property is good even on a plastic surface containing a plasticizer, and the adhesive strength after application is reduced. An object of the present invention is to provide a surface protective film which has a small amount of adhesive residue on an adherend and has good weather resistance.

Hydrogenated terpene resins and hydrogenated aliphatic petroleum resins are preferred. The compounding amount is 20 to 150 parts by weight based on 100 parts by weight of the acid-modified SEBS . If the amount of the tackifier is less than 20 parts by weight, the workability is poor because the initial adhesive strength is low and the adhesive is easily peeled off. When the amount of the tackifier exceeds 150 parts by weight, the adhesive strength is so strong that it is difficult to peel off from the adherend after use. The preferred amount is 30 to 130 parts by weight, particularly 60 to 130 parts by weight.

Of the adhesive can be suppressed, and the adhesive can be prevented from remaining on the adherend. When the amount of the epoxy resin is less than 0.1 part by weight, the crosslinking reaction does not sufficiently proceed, and the adhesive remains on the adherend. If the amount is more than 5 parts by weight, the crosslink density becomes too high, and the initial adhesion at the time of laminating is problematic. The preferred amount is 0.3
