    • To provide an easily releasable adhesive film that can be easily released from an object, to which the film has been bonded, after processing and that does not deform or damage the object when released therefrom. This easily releasable adhesive film is configured by laminating, in the following order, a first film that is thermally shrinkable (a shrinkable film), an adhesive layer that contains a reactive oligomer together with an adhesive, a second film that is not thermally shrinkable (a non-shrinkable film), and an easily releasable adhesive layer. The reactive oligomer is contained in the adhesive layer in an amount of 12 to 130 parts by weight (inclusive) relative to 100 parts by weight of the adhesive. It is preferable that the easily releasable adhesive layer is configured as an easily releasable adhesive layer that is thermally curable/releasable and contains a reactive oligomer together with an adhesive. It is also preferable that the first film has a shrinkage of 50-90% (inclusive) in the main shrinkage direction at 120° C.
    • 为了提供一种容易释放的粘合剂膜,其可以在加工后容易地从被粘合的物体释放,并且在物体释放时不会变形或损坏物体。 这种容易剥离的粘合剂膜通过以下顺序层叠第一热可收缩膜(可收缩膜),含有反应性低聚物和粘合剂的粘合剂层,不能热收缩的第二膜 不可收缩膜)和易剥离的粘合剂层。 相对于100重量份的粘合剂,反应性低聚物的含量为12〜130重量份(含)的粘合剂层。 优选地,易剥离性粘合剂层被构造为可热固化/可释放的容易剥离的粘合剂层,并且与粘合剂一起含有反应性低聚物。 也优选第一膜在120℃下的主收缩方向的收缩率为50-90%(含)。
