Gas barrier layered product and method for producing the same |
摘要 |
The gas barrier layered product of the present invention includes a base and a gas barrier layer. The gas barrier layer is formed of a composition that includes a hydrolyzed condensate of a compound (L) and a neutralized product of a polymer (X) containing a carboxyl group or a carboxylic acid anhydride group. The compound (L) includes a specific compound (A) that contains M1 (Al, Ti, or Zr) to which a hydrolyzable characteristic group is bonded and a specific compound (B) that contains Si to which a hydrolyzable characteristic group is bonded. At least part of -COO- group of the polymer (X) is neutralized with a metal ion having a valence of at least two. At least 80 mol % of the compound (B) is a compound expressed by a specific formula. The ratio of [the number of moles of M1 in the compound (A)]/[the number of moles Si in the compound (B)] is in the range of 0.1/99.9 to 30.0/70.0. |
