Abstract:
The invention makes it possible to use a coating liquid of a fine cellulose fiber (a natural material) and to form a coated layer which can be used as a various-functions layer such as a gas barrier layer and water vapor barrier layer etc. by achieving good adhesiveness and coatability of the coating liquid, and as a result, provides a laminated material in which temporal degradation of a substrate and the fine cellulose fiber layer is prevented. The laminated body includes a substrate, an anchor layer arranged on a surface the substrate, and a fine cellulose fiber layer containing a fine cellulose fiber having a carboxy group, wherein the anchor layer contains at least one resin having a carboxy group, sulfonate group, amino group or hydroxyl group.
