  • Patent number: 9622985
    Abstract: The present invention provides a patch or patch preparation in which the anchoring property of a pressure-sensitive adhesive layer to a support is improved with no adverse effects on its pressure-sensitive adhesive properties such as adhesion, pressure-sensitive adhesiveness, and a cohesive strength. A support of the present invention is for a patch or patches preparation, and comprises a base material containing a plastic film and an undercoat agent layer laminated on the base material. The undercoat layer contains porous inorganic particles having an average particle diameter of from 1 ?m to 15 ?m. A patch and patch preparation of the present invention comprises the support and a pressure-sensitive adhesive layer placed on one surface of the support to be adjacent to the undercoat agent layer.
