One of the purposes of the present invention is to provide a silicone adhesive composition which provides an adhesive layer having an excellent antistatic property and which has an excellent bond strength to a tape substrate and, therefore, when an adhesive tape or film having the adhesive layer is peeled from a tape-stuck body, less residual adhesive occurs on the tape-stuck body. The other purpose of the present invention is to provide a silicone adhesive composition which cures well by heating for a short time, particularly for less than 5 minutes, to provide an adhesive layer having an excellent antistatic property. The present invention first provides a silicone adhesive composition comprising (A) an addition reaction-curable silicone, (B1) a compound having at least two unsaturated hydrocarbon groups and two (poly)oxyalkylene residues in one molecule, and (C) an ionic liquid containing no lithium. The present invention secondly provides a silicone adhesive composition comprising (A) an addition reaction-curable silicone, (B) a compound having at least one unsaturated hydrocarbon group and at least one (poly) oxyalkylene residue in one molecule, (C) an ionic liquid containg no lithium and (e) a platinum group metal catalyst which is not a complex with a compound having an unsaturated hydrocarbon bond.
本发明的目的之一是提供一种硅酮粘合剂组合物,该组合物提供的粘合剂层具有极佳的抗静电性能,并且与胶带基材具有极佳的粘合强度,因此,当具有该粘合剂层的胶带或薄膜从胶带粘贴体上剥离时,胶带粘贴体上的残留粘合剂较少。本发明的另一个目的是提供一种硅酮粘合剂组合物,该组合物通过短时间,特别是少于 5 分钟的加热就能很好地固化,从而提供具有优异抗静电性能的粘合层。本发明首先提供了一种有机硅粘合剂组合物,该组合物包括(A)加成反应固化的有机硅,(B1)在一个分子中具有至少两个不饱和烃基和两个(聚)氧烷基残基的化合物,以及(C)不含锂的离子液体。本发明其次提供了一种有机硅粘合剂组合物,该组合物包含 (A) 加成反应固化有机硅,(B) 在一个分子中具有至少一个不饱和烃基和至少一个(聚)氧烷基残基的化合物,(C) 不含锂的离子液体,以及 (e) 不与具有不饱和烃键的化合物形成络合物的铂族金属催化剂。
