<p><P>PROBLEM TO BE SOLVED: To develop a method of stably manufacturing a gas barrier film showing excellence in transparency and a gas barrier property under high humidity without applying crosslinking heat treatment under a high temperature of 180 to 200°C to an unsaturated carboxylic compound. <P>SOLUTION: The manufacturing method of the gas barrier film comprises applying a solution of a polyvalent metal salt of unsaturated carboxylate compound of a polymerization degree of less than 20 to a base layer, preliminarily polymerizing the polyvalent metal unsaturated carboxylate compound, and polymerizing the same, preferably polymerizing the same after partly drying the applied liquid. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
