【発明の詳細な説明】
〔産業上の利用分野］
本発明はエチレン系ポリマーとポリシロキサン系重合体
の混練物から製造された剥離性シートに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a releasable sheet manufactured from a kneaded product of an ethylene polymer and a polysiloxane polymer.
壁紙、ラベル、シール、ワッペン、粘着テープ、マスキ
ングテープ、マスキングフィルム、仮着性保護フィルム
等は、プラスチック、金属バルブ等の材料から製造され
たフィルム、シート、箔、紙等の支持体の一面又は両面
に接菅剤又は粘着剤の看（本明細書ではこれらをまとめ
て単に粘着剤層という）を設けた積層体であり、保管時
には粘着剤層が他の物体に接着しない様にし、使用時に
は容易に粘着剤層が表面にでる様にするために、粘着剤
層は剥離性シートで被覆されている。Wallpaper, labels, stickers, patches, adhesive tapes, masking tapes, masking films, temporary adhesive protective films, etc. are made from materials such as plastics and metal valves, and are made from one side of a support such as a film, sheet, foil, or paper. It is a laminate with adhesive or adhesive coatings on both sides (in this specification, these are simply referred to as adhesive layers), and the adhesive layer is prevented from adhering to other objects during storage, and when used. In order to easily expose the adhesive layer to the surface, the adhesive layer is covered with a releasable sheet.
この従来の剥離性シートは支持体の背面に、シリコーン

もの：等を処理したものである。This conventional release sheet uses silicone release agents, waxes, fluorine release agents, long-chain acrylate polymers, polymers with reactive groups such as polyvinyl alcohol, cellulose, and polyethyleneimine on the back side of the support, such as alkyl isocyanate, chloride, etc. Products with side chains introduced with alkylyl, etc. are processed.
［発明が解決しようとする課題）
しかしながら、これら従来の剥離性シートには次のよう
な問題がある。まずシリコーン系剥離剤は、剥離処理時

ない。[Problems to be Solved by the Invention] However, these conventional releasable sheets have the following problems. First of all, silicone release agents require high-temperature heat treatment during the release process, so they may not be able to be used on supports with poor heat resistance such as OPP and polyethylene. This is undesirable because it has a negative effect on electrical components.
ワックス系は安価であるが、移動性がはげしく、粘着テ
ープ等の粘着効果を低下させてしまう危険性がある。Although wax-based materials are inexpensive, they have high mobility and have the risk of reducing the adhesive effect of adhesive tapes and the like.
フッ素系剥離剤には比較的高価であるという問題がある
。A problem with fluorine-based strippers is that they are relatively expensive.
長鎖アクリレート重合物は、移行性、耐熱性が不十分で
あり、アルキル化ポリマータイプはやや作業性に問題が
あり、均一な剥離被膜がつくりにくい。Long-chain acrylate polymers have insufficient migration properties and heat resistance, and alkylated polymer types have some problems in workability, making it difficult to form a uniform release film.
本発明は、支持体の背面に各種剥離剤を処理してなる従
来の剥離性シートの問題を解決する目的でなされたもの
であり、その解決しようとする課題は、高熱処理を必要
とせず剥離剤の移行の問題が無く、安価でしかも膜厚が
均一な剥離性シートを提供することである。The present invention was made for the purpose of solving the problems of conventional releasable sheets made by treating the back side of a support with various release agents. To provide a releasable sheet which is inexpensive and has a uniform thickness without the problem of agent migration.
［課題を解決するための手段］
本発明者等は、支持体の背面に各種剥離剤を処理すると
前記の様な各種の問題を生じるので支持体自体に剥離性
を付与すれば前記問題が解決できることを見い出し、本
発明を完成させた。[Means for Solving the Problems] The present inventors believe that treating the back surface of a support with various release agents causes various problems as described above, and that the above problems can be solved by imparting releasability to the support itself. They discovered what could be done and completed the present invention.

0 parts by weight, and the following formula (A): R+, R”bS i O4-a-b
(A) (wherein R' is an aliphatic unsaturated group, R2 is an unsubstituted or substituted 1 containing no aliphatic unsaturated group)
represents a valence hydrocarbon group, and a and b satisfy the following condition: 0≦a
<1.0.5<b<3.1<a+b<3) A kneaded product having a gel content of 10% or more obtained by heating and kneading 10 to 900 parts by weight of an organopolysiloxane represented by It is characterized by being formed by forming a film.

明はそうしたテープや物品にも関する。The releasable sheet of the present invention does not cause the problem of migration of the release agent to the adhesive layer unless it oozes onto the surface, so it is convenient to use it for adhesive tapes or other adhesive products. Also relates to tapes and articles.
