Patent ID: 8900681

Claim:
A layered product, comprising: a base; and a gas barrier layer stacked on the base, wherein the gas barrier layer comprises a composition comprising a hydrolyzed condensate of a compound (L) comprising a hydrolyzable group and a neutralized product of a polymer (P) comprising at least one functional group selected from the group consisting of a carboxyl group and a carboxylic acid anhydride group, wherein: the compound (L) comprises a compound (L 1 ) comprising an organic group comprising an amino group, and a compound (L 2 ), which does not comprise an organic group comprising an amino group; the compound (L 1 ) and the compound (L 2 ) each comprises a silicon atom bonded to the hydrolyzable group; and at least a part of —COO— group in the at least one functional group 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, wherein the base is in the form of a film, and the gas barrier layer comprises a first gas barrier layer stacked on one surface of the base, and a second gas barrier layer stacked on a second surface of the base, and wherein a ratio of a total number of moles of the amino group in the compound (L 1 ) in the first gas barrier layer, (NA1), to a total number of moles of the —COO— group in the at least one functional group in the polymer (P) in the first gas barrier layer, (NC1), satisfies a relation: 0.4/100≦(NA1/NC1)≦2.0/100, and wherein a ratio of a total number of moles of the amino group in the compound (L 1 ) in the second gas barrier layer, (NA2), to a total number of moles of the —COO— group in the at least one functional group in the polymer (P) in the second gas barrier layer, (NC2), satisfies a relation: 2.0/100<(NA2/NC2)≦11.0/100.
