Abstract

A laminate has at least one polylactic acid resin-containing layer (C) with a thickness of 10-500 nm on at least one surface of a fibrous structure (B) containing a water-soluble resin (A). A production method for the laminate is characterized in that water or an aqueous solution is applied to the joining surface of the fibrous structure (B) and the polylactic acid resin-containing layer (C). The laminate exhibits excellent followability, adherence and coatability relative to flexible, curved adherends, exhibits excellent compatibility to organs such as skin and internal organs, and, because the fibrous structure (B) containing a water-soluble resin (A) can easily be removed from the polylactic acid resin-containing layer (C) by the aqueous solution, is adapted for use in materials for external use on the skin, such as wound-dressing materials, adhesion-preventing materials, and skin care products.
