Abstract:
An adhesive patch comprising: a support; at least a pressure-sensitive adhesive layer provided on the support; and a release liner attached on the pressure-sensitive adhesive layer so as to cover the surface of the pressure-sensitive adhesive layer, in which the support is a 3D patterned sheet characterized in that a plurality of protruded lines and recessed lines parallelly and linearly extending are formed inside and outside lines in a plurality of figures partitioned by the lines, walls of the protruded lines and recessed lines in some of the figures are formed to be inclined by different inclination angles with respect to a base part, and the protruded lines have different heights from the base part, serving as physical parameters of the protruded lines and recessed lines, toward a predetermined direction in the sheet.
