る。(Prior art/problem to be solved by the invention) Conventionally, as a surface protection peripheral adhesive film, a polyolefin film such as polyethylene, polypropylene, or a blend of polyethylene/polypropylene is used as a support, and a pressure-sensitive adhesive (synthetic Rubber materials such as rubber, acrylic resin)
A pressure-sensitive adhesive layer is formed by coating the adhesive. However, since such films and pressure-sensitive adhesives deteriorate in a short period of time due to exposure to sunlight, etc. (mainly due to the effects of ultraviolet rays), the film may be destroyed when removed, or the pressure-sensitive adhesive may remain on the protected surface. There are other problems. In order to solve the above problems, it has been considered to incorporate known ultraviolet absorbers, antioxidants, and light stabilizers into the polyolefin resin support, but polyolefin resins are generally compatible with these additives. Since the additive is not good, the additive bleeds onto the surface over time and is removed by rain, etc., so its content decreases and is not sufficient to prevent deterioration of the film or pressure-sensitive adhesive. Further, a method of mixing these additives into a pressure-sensitive adhesive has been studied, but there is still a problem that the additives are absorbed onto the surface when the additives are taken orally and contaminate the adherend. In addition, consideration is being given to making the support layer a two-layer structure and incorporating these additives into the pressure-sensitive adhesive and the layer on which the adhesive is applied to suppress bleeding of additives to the surface over time. However, with this type, the additive bleeds into the interface between the support and the pressure-sensitive adhesive, which reduces the anchoring ability of the pressure-sensitive adhesive to the support, and when the film is peeled off, the pressure-sensitive adhesive bleeds into the interface. There is a problem that the adhesive remains on the surface of the adherend.
