    摘要: The purpose of the present invention is to provide a laminated film that is highly biocompatible and easy to handle, has good pasting ability and contact to an organ tissue and rarely induces infections. The laminated film provided by the present invention, which comprises a polylactic acid-based resin layer and one or more acetylated hyaluronic acid layers laminated on a side of the polylactic acid-based resin layer, is highly flexible and easy to handle, and, when stuck to an adherend with curved surface, the laminated film shows excellent followability, adhesiveness and coating properties to the adherend, since the acetylated hyaluronic acid layer(s) can be removed easily with an aqueous solution from the polylactic acid-based resin layer in a thin film shape. Moreover, the acetylated hyaluronic acid and the polylactic acid-based resin are biodegradable and, therefore, the laminated film is highly compatible with skin and organs such as visceral organs, etc. Thus, the laminated film is optimally usable as a dermal material for external application such as a wound coating material, an adhesion inhibitor and skin care articles.
