METHOD OF PRODUCING GAS-BARRIER LAMINATED MEMBER |
摘要 |
A method of producing a gas-barrier laminated member having a gas-barrier layer formed by crosslinking the carboxyl groups of a polycarboxylic acid polymer with multivalent metal ions. The method comprises forming a layer (A) containing an alkaline compound of a multivalent metal on at least one surface of a plastic base material, applying a solution (b) obtained by dissolving a polycarboxylic acid polymer in a solvent containing at least water onto the layer (A) that contains the alkaline compound of the multivalent metal, and removing the solvent by a heat treatment so that a metal-ionically crosslinked structure is formed with the multivalent metal ions among the carboxyl groups in the solution (b). The gas-barrier laminated member has excellent adhesion to the base material, gas-barrier property, retort resistance and flexibility, and is efficiently produced by only being heated at a low temperature for a short period of time through a decreased number of simplified steps. |
