Zusammenfassung: | To provide a resin composition for living body by which an adhesive layer having excellent handling easiness and retentivity can be formed, and an adhesive sheet for living body which contains an adhesive layer formed of a composition containing the resin composition.SOLUTION: A resin composition for living body contains: (meth)acrylic polymer containing 50 mass% to 94.5 mass% of constitutional unit A derived from (meth)acrylic acid alkyl ester, whose glass-transition temperature is 0°C or higher in the case of homopolymer, with respect to the total constitutional unit, 5 mass% to 49.5 mass% of constitutional unit B derived from (meth)acrylic acid alkyl ester, whose glass-transition temperature is -50°C or lower in the case of homopolymer, with respect to the total constitutional unit, and 0.5 mass% to 10 mass% of constitutional unit C derived from monomer having carboxy group with respect to the total constitutional unit; and surfactant.SELECTED DRAWING: None
【課題】取扱い容易性と保持性とに優れる粘着剤層を形成できる生体用樹脂組成物、及び該樹脂組成物を含む組成物から形成された粘着剤層を含む生体用粘着シートを提供する。【解決手段】ホモポリマーとしたときのガラス転移温度が0℃以上である(メタ)アクリル酸アルキルエステルに由来する構成単位Aを全構成単位に対して50質量%〜94.5質量%と、ホモポリマーとしたときのガラス転移温度が−50℃以下である(メタ)アクリル酸アルキルエステルに由来する構成単位Bを全構成単位に対して5質量%〜49.5質量%と、カルボキシ基を有するモノマーに由来する構成単位Cを全構成単位に対して0.5質量%〜10質量%と、を含む(メタ)アクリル系ポリマーと、界面活性剤と、を含む生体用樹脂組成物。【選択図】なし |
