LAMINATE HAVING GAS BARRIER PROPERTIES, AND MANUFACTURING METHOD THEREFOR

摘要

Provided is a laminate having gas barrier properties, which comprises a substrate and a gas barrier layer. The gas barrier layer comprises a composition of: a hydrolyzed condensation of a compound (L), and a neutralized polymer (X) containing a carboxyl group or a carboxylic acid anhydride group. The compound (L) comprises: a specific compound A which includes M1 (aluminum, titanium, or zirconium) with a hydrolyzable characteristic group bonded thereto; and a specific compound B which includes silicon with a hydrolyzable characteristic group bonded thereto. At least part of the -COO- group of the polymer (X) is neutralized by a metallic ion having a valence of at least 2. At least 80 mol% of compound B is a compound represented by a prescribed formula. The ratio between the number of moles of M1 in compound A and the number of moles of silicon in compound B is between 0.1 to 99.9 and 30.0 to 70.0.
