LAMINATE, PACKAGING MATERIAL USING SAME, MOLDED ARTICLE, AND METHOD FOR PORDUCING THE LAMINATE

摘要

The layered product of the present invention has a base, and a gas barrier layer stacked on the base. The gas barrier layer is formed of a composition that includes a hydrolyzed condensate of a compound (L) containing a hydrolyzable characteristic group, and a neutralized product of a polymer (P) containing at least one functional group selected from the group consisting of carboxyl group and carboxylic acid anhydride group. The compound (L) includes a compound (L 1 ) and a compound (L 2 ). The compound (L 1 ) and the compound (L 2 ) each contains a silicon atom to which the hydrolyzable characteristic group is bonded. The compound (L 1 ) contains an organic group having amino group. The compound (L 2 ) does not contain an organic group having amino group. At least part of the -COO- group in the at least one functional group contained in the polymer (P) is neutralized with a divalent or higher valent ion (E) of a metal element that has a higher electronegativity than calcium.
