Disclosed is a material that effectively utilizes natural resources and is friendly to the environment as a whole. Specifically, disclosed is a barrier material that has excellent strength and excellent affinity and adhesion to a paper base due to an interaction with paper fibers and that gives sufficient barrier properties even in the form of a thin film. A laminated body () includes, on at least one surface of a base () made of paper, a fiber layer () containing fine cellulose fibers each having a fiber diameter of 1 nm or more and 10 &#x3bc;m or less. In particular, the fine cellulose fibers preferably have a fiber diameter of 1 nm or more and 30 nm or less.

Laminated body, method for producing the same, and molded container

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.

Laminated body

An antistatic laminate and a laminate material equipped with the laminate are provided, wherein the laminate includes a base material and an antistatic layer which comprises a cellulose fiber having a carboxyl group, and the laminate can prevent deterioration of antistatic properties under a low humidity environment, while high transparency is maintained due to use of a material wherein natural resources are effectively used.
