PROBLEM TO BE SOLVED: To provide an adhesive patch and a patch preparation which are reduced in skin irritation that occurs during wearing.SOLUTION: The adhesive patch is controlled so that : (a) a surface of an adhesive layer has a logarithmic decrement measured by the rigid-pendulum free-damped oscillation method in the range of 0.03 to 0.35, and (b) the adhesive layer has a maximum shear displacement in the range of 18 &mum to 1,000 &mum when a shear stress is imposed on the adhesive layer.COPYRIGHT: (C)2012,JPO&INPIT【課題】貼付中に生じる皮膚刺激の低減された貼付剤および貼付製剤を提供する。【解決手段】(a)剛体振子自由振動法で測定される粘着剤層表面の対数減衰率が0.03~0.35、(b)粘着剤層に剪断応力を与えた際の粘着剤層の最大剪断変位量が18μm~1,000μmの範囲内となるように制御する。【選択図】なし
