PROBLEM TO BE SOLVED: To provide a patch support for a water-based plaster excellent in plaster-holding properties and water-holding properties, inhibiting the sublimation of a drug to improve the long-lasting drug effect, imparting neither restricted feeling nor roughness to a wearer due to the thinness and preferable flexibility thereof, and controlled moisture-permeability and little stickiness to thereby comfort the wearer.SOLUTION: The patch support for a water-based plaster is a laminate consisting of three layers laminated together, i.e., a non-woven fabric layer A, a non-woven fabric layer B and a film layer having through-holes, the film layer being positioned between the non-woven fabric layers A and B, wherein the film layer is formed of a resin comprising an olefin-based elastomer, and through-holes have an area of 0.02-0.18 mm2 per hole and a porosity of 1-10%.COPYRIGHT: (C)2012,JPO&INPIT【課題】膏体保持性及び保水性に優れ、膏体中の薬剤の昇華を抑制して薬効持続性を向上させ、薄くて良好な伸縮性により拘束感やゴワツキを感じず、透湿性を制御してベタツキも感じ難い着用感の良好な水性膏体用貼付支持体の提供。【解決手段】不織布層Aおよび不織布層B間に貫通孔を有するフィルム層が積層された三層からなる積層体であって、そのフィルム層がオレフィン系エラストマーを含有する樹脂で構成され、貫通孔が1個当りの面積が0.02~0.18mm2の貫通孔であり、開孔率が1~10%である積層体からなる水性膏体用貼付支持体。【選択図】なし
