いう問題点がある。Conventionally, A-B has been used as an adhesive for surface protection adhesive films, which shows little change in adhesive strength even if left for a relatively long time.
A block copolymer represented by -A (wherein A represents a styrene polymer block and B represents an ethylene and butylene copolymer block) is blended with a tackifying resin. Adhesives have poor anchoring properties with olefin resin films such as polyethylene and polypropylene films used as surface protection films (i.e., supports), so there is a possibility that the adhesive will not be able to anchor between the surface protection film, which is a support layer, and the adhesive layer. There is a problem in that interfacial destruction occurs and adhesive residue is generated.

However, there remains the technical issue of controlling the fluidity of the adhesive layer inside the mold.

物を提供することである。Therefore, an object of the present invention is to provide a pressure-sensitive adhesive composition for a surface protection pressure-sensitive adhesive film that has extremely excellent anchoring power to a surface protection film that is a support. That is, even if a surface protection adhesive film manufactured by applying the adhesive composition to an olefin resin film such as polyethylene or polypropylene is stored for a long period of time, no adhesive remains and it can be easily peeled off. An object of the present invention is to provide a pressure-sensitive adhesive composition.

粘着力を測定する。(Test Method) Adhesive Crab 5US430BA is temporarily attached with a 25 nm wide adhesive film for surface protection as a test piece using a 2 kg pressure roller. This test piece was tested at a temperature of 23°C±2°C and a humidity of 65±15%R.
After being left in H for 1 hour or more, it was pulled at a speed of 300+ nm per minute using a Schopper pendulum type tensile tester to measure the 180° peel adhesive strength.

0m/分のスピードで剥離した時、被着体に貼着剤が残
るかどうか判定する。Adhesive residue after 60°C x 30 days: The above test piece was placed in a heating oven at 60°C ± 2°C, and after being stored for 30 days, it was left under normal conditions for more than 2 hours, and the adhesive remained for about 10 days.
It is determined whether the adhesive remains on the adherend when it is peeled off at a speed of 0 m/min.

本発明の表面保護粘着フィルム用粘着剤組成物は、表面
保護用フィルムに対する投錨力に優れており、当該粘着
剤組成物を用いて製造された表面保護用粘着フィルムを
貼付して長刀間高温所、屋外等に放置した後においても
、粘着剤が板状物品に残ることなく容易に剥離すること
ができるという効果を有する。The adhesive composition for a surface protection adhesive film of the present invention has excellent anchoring power for a surface protection film, and the adhesive composition for surface protection produced using the adhesive composition can be attached to a high-temperature place. This has the effect that the adhesive does not remain on the plate-shaped article and can be easily peeled off even after being left outdoors or the like.
また、本発明の表粘着剤組成物は投錨性に優れるため、
当該粘着剤組成物を用いて製造された表面保護用粘着フ
ィルムの貼合せ作業時に誤って接着剤面同士が接着した
場合でも、粘着剤層が脱落することなく剥離することが
できるという効果を有する。In addition, since the surface adhesive composition of the present invention has excellent anchoring properties,
Even if the adhesive surfaces accidentally adhere to each other during lamination of a surface protection adhesive film produced using the adhesive composition, the adhesive layer can be peeled off without falling off. .
