<P>PROBLEM TO BE SOLVED: To obtain a gas-barrier laminated film that is transparent, having superior gas barrier properties, such as oxygen, carbon dioxide, water vapor, etc. especially in gas barrier properties under high humidity. <P>SOLUTION: A method of manufacturing a gas-barrier laminated film is characterized by polymerizing the unsaturated carboxylic acid compound polyvalent metal salt to an unextended or extended base material layer (X), after coating the solution (s) containing unsaturated carboxylic acid compound polyvalent metal salt of less than 20 in polymerization degree, and carrying out laminate of layer (W) and other layers, after providing a layer (W) comprising the adhesive resin (c) to the layer (Y) of gas barrier film obtained from forming a layer (Y) containing a polymer (a) of unsaturated carboxylic acid compound polyvalent metal salt. <P>COPYRIGHT: (C)2012,JPO&INPIT |
