Description

すなわち、本発明は、炭素数１〜２０の（メタ）アクリル酸アルキルエステルがポリマーを構成するモノマー成分全量に対して６０重量％以上であるアクリル系ポリマーと気泡と中空微小球状体を含有し、且つ界面活性剤を含有する粘弾性組成物であって、前記界面活性剤が分子中にオキシＣ2-3アルキレン基及びフッ素化炭化水素基を有するフッ素系界面活性剤であることを特徴とする気泡含有粘弾性組成物である。 That is, the present invention comprises an acrylic polymer, a bubble and a hollow microsphere having a C1-C20 (meth) acrylic acid alkyl ester of 60 wt% or more based on the total amount of monomer components constituting the polymer And a viscoelastic composition containing a surfactant, wherein the surfactant is a fluorinated surfactant having an oxy-C 2-3 alkylene group and a fluorinated hydrocarbon group in the molecule. It is a bubble-containing viscoelastic composition.

本発明は、さらにまた、基材の少なくとも一方の面に感圧性接着剤層を有している感圧性接着テープ又はシートであって、基材が、前記気泡含有粘弾性組成物により形成されていることを特徴とする感圧性接着テープ又はシートである。尚、本明細書には上記発明の他に、気泡と中空微小球状体を含有し且つ界面活性剤を含有する粘弾性組成物であって、前記界面活性剤が、分子中にオキシＣ 2-3 アルキレン基及びフッ素化炭化水素基を有するフッ素系界面活性剤であることを特徴とする気泡含有粘弾性組成物についても記載する。
The present invention is also a pressure-sensitive adhesive tape or sheet having a pressure-sensitive adhesive layer on at least one surface of a substrate, wherein the substrate is formed of the bubble-containing viscoelastic composition. A pressure-sensitive adhesive tape or sheet. In addition to the above-described invention, the present specification includes a viscoelastic composition containing bubbles and hollow microspheres and containing a surfactant, wherein the surfactant contains oxy-C 2- also described the bubble-containing viscoelastic composition, which is a fluorine-based surfactant having a 3 alkylene group and a fluorinated hydrocarbon group.
