<P>PROBLEM TO BE SOLVED: To provide an adhesive patch and a patch preparation which are reduced in skin irritation that occurs during wearing. <P>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 μm to 1,000 μm when a shear stress is imposed on the adhesive layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
