Laminate having gas barrier properties, and manufacturing method therefor |
摘要 |
The gas barrier layered product of the present invention includes a base and a gas barrier layer stacked on the base. The gas barrier layer is formed of a composition that includes the hydrolyzed condensate of at least one type of compound (L) containing a hydrolyzable characteristic group, and a polymer (X) containing at least one functional group selected from a carboxyl group and a carboxylic acid anhydride group. At least part of -COO- group contained in the functional group of the polymer (X) is neutralized and/or reacted with a compound (P) containing at least two amino groups. At least part of the -COO- group of the polymer (X) is neutralized with a metal ion having a valence of at least two. The ratio of [the equivalent amount of the amino groups contained in the compound (P)]/[the equivalent amount of the -COO- group of the polymer (X)] is in the range of 0.2/100 to 20.0/100. |
