PROBLEM TO BE SOLVED: To provide a skin adhesive sheet with high oxygen permeability which has a good adhesiveness to the skin surface, hardly dry even if using for a long time, can maintain flexibility, and has little change of shape by using silicone-containing copolymer with lower water content.SOLUTION: A skin adhesive sheet consists of a copolymer of the following component A and component C. Component A: polysiloxane macro monomer having two or more polymerizing functional groups per molecule, and having a number average molecular weight of 6000 or more. Component C: polymerizing monomer which has an alkyl group and does not have a fluoro alkyl group.COPYRIGHT: (C)2016,JPO&INPIT【課題】高い酸素透過性を有し、含水率がより低いシリコーン含有共重合体を用いることによって、皮膚表面との粘着性が良好で、長時間使用しても乾燥し難く、柔軟性を保つことができ、かつ形状の変化が少ない皮膚粘着シートを提供することを目的とする。【解決手段】下記成分A及び成分Cの共重合体からなる皮膚粘着シート。成分A:1分子あたり複数の重合性官能基を有し、数平均分子量が6000以上のポリシロキサンマクロモノマー成分C:アルキル基を有し、フルオロアルキル基を有しない重合性モノマー【選択図】なし
