Abstract
The present invention relates to a backing having a three-layer structure prepared by sticking together an inner fiber layer for holding a pasty preparation, a film layer having through-holes, and an air-permeable outer fiber layer which prevents leaking out of the pasty preparation or a liquid component exuded from the pasty preparation, and also relates to an aqueous patch using the backing which can be applied for a long time.
