Abstract:
1. A gas barrier multilayer structure precursor comprising a support and a gas barrier layer precursor formed on the support, the gas barrier layer precursor comprising a layer (A) and a layer (B), the layer (A) comprising a polycarboxylic acid polymer and at least one silicon-containing compound (i) selected from the group consisting of silane coupling agents represented by Formula (1) below, hydrolysates thereof and condensates of these compounds, the weight ratio of the polycarboxylic acid polymer and the silicon-containing compound(s) (i) in the layer (A) (the weight of the silicon compounds (i) other than the silane coupling agents is in terms of silane coupling agents) being in the range of 99.5:0.5 to 80.0:20.0, the layer (B) comprising a polyvalent metal compound, the layer (A) isolated from the support and the layer (B) and analyzed by a transmission method showing an infrared absorption spectrum in which the maximum peak height (α) in the range of 1490 to 1659 cm wherein R is a C1-6 alkyl group, Z is an organic group containing a glycidyloxy or amino group, and a plurality of R may be the same or different from one another.
