するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to prevent O'RWJK from attaching plate-like articles such as metal plates, decorative plates, glass, and resin plates, and to prevent dust from adhering to or being damaged by these articles. This article relates to a protective adhesive II composition (hereinafter referred to as an adhesive composition) K used for a protective adhesive film or &-) used for surface protection. The object of the present invention is to provide an adhesive composition that has appropriate adhesion properties, has almost no increase in adhesive strength even after a period of time, and can be easily removed.
表面保護用粘着フィルム(以下粘着フィルムという)は
、ゴミ付着防止、表面損傷防止など所明の目的が達成さ
れると剥離されるものである。A surface protection adhesive film (hereinafter referred to as an adhesive film) is peeled off when a predetermined purpose, such as preventing dust from adhering to the surface or preventing damage to the surface, is achieved.
これまでかかる粘着フィルムには、アクリル系感圧接着
剤組成物、天然ゴム又はポリイソプレンゴム系感圧接着

を板状物品の表面に貼り付けて長明間保存しておくと、
経日で接着力が上昇するために剥離が困感であったり、
剥離しえても板状物品面に多量の糊残りがするといつた
問題がありた。Adhesive compositions such as acrylic pressure-sensitive adhesive compositions, natural rubber or polyisoprene rubber pressure-sensitive adhesive compositions have been used for such adhesive films to date, and adhesive compositions such as acrylic pressure-sensitive adhesive compositions, natural rubber or polyisoprene rubber-based pressure-sensitive adhesive compositions have been used on the surface of plate-shaped articles. If you paste it and save it for a long time,
It may be difficult to peel off because the adhesive strength increases over time, or
Even if the adhesive could be peeled off, there was a problem in that a large amount of adhesive remained on the surface of the plate-shaped article.
かかる開明を解決する手段として、接着剤組成物に界面

を経時的に接着剤層と板状物品との界面Kitみ出させ
て非接着性の薄膜状物を形成させ、経日での接着力の上
昇を防止するものである。As a means to solve this problem, a method of incorporating a surfactant or a silicone composition as a release modifier into an adhesive composition has been proposed and has been partially implemented. In this method, a surfactant or a V9 Poon composition blended in an adhesive composition is allowed to ooze out over time from the interface between an adhesive layer and a plate-like article to form a non-adhesive thin film-like material. This prevents the adhesive strength from increasing over time.

加工時にフィルムが板状物品面より浮いたり、或いはフ
ィルムを剥がしたときに板状物品面に薄膜状物が残留し

生させたりするといった不都合がある。However, this method has the disadvantage that it is difficult to obtain a stable peeling effect because the amount of seepage varies depending on the type and thickness of the adhesive layer. If the film is heated in this condition, oozing will occur rapidly and the adhesive force will decrease, and the film may float above the surface of the plate-shaped object during processing such as sheet metal processing, or when the film is peeled off, it may bleed onto the surface of the plate-shaped object. There is a problem that a thin film-like substance remains, which causes printing unevenness during a subsequent printing process.

This is undesirable because it significantly reduces the adhesion to the brush.
