A device for the production of a thin plate laminate includes a setting device for creating a mold retention structure in which the molds are arranged on both surface sides of the workpiece, a heating device for heating the molds, a compression roller device in which the mold retention structure is introduced between two compression rollers and which compresses outer surfaces of the molds by rotating the compression rollers to integrally thermocompression-bond film resin composition and the substrate to form a thin plate laminate having the film resin layer, and an extraction device for extracting the mold retention structure after compression from the molds.

Device for production of thin plate-like laminate having film-like resin layer

[Object] To provide a method for the production of a thin plate-like laminate having a film-like resin layer in which a concave/convex shape can stably be formed with high accuracy on the film-like resin layer laminated on a thin plate-like substrate. [Achieving Means] There are provided a step of creating a mold retention structurein which molds, which have been heated to a thermal deformation temperature of a film-like resin composition, are arranged on both surface sides of a workpiece, and a step of introducing the mold retention structure in which the heated molds are arranged between two compression rollersand compressing outer surfaces of the molds by rotating the compression rollers to integrally thermocompression-bond the film-like resin composition and a substrateto form a thin plate-like laminatehaving a film-like resin layer

An aqueous resin composition with gas barrier properties contains (i) polyurethane resin having aurethane group and a urea group in a total concentration of 25 to 60% by weight and having a acid value of 5 to 100 mgKOH/g, (ii) a swelling inorganic layered compound (e.g., a water-swelling mica, and a montmorillonite), and (iii) a polyamine compound having an amine value of 100 to 1900 mgKOH/g. The polyurethane resin (i) is obtained by a reaction of (A) an aromatic, araliphatic or alicyclic polyisocyanate, (B) a polyhydroxyalkanecarboxylic acid, and at least one component selected from (C) a Calkylene glycol and (D) a chain-extension agent (e.g., diamine, hydrazine and a hydrazine derivative), and neutralized with a neutralizing agent. The proportion of the acid group of the polyurethane resin (i) relative to the basic nitrogen atom of the polyamine compound (iii) is 10/1 to 1/5 as the equivalent ratio. A laminated film with high gas barrier properties is obtainable by coating a base film with the aqueous resin composition. The present invention provides an aqueous resin composition with excellent gas barrier properties, and a laminated film using the same.
