Abstract: A gas barrier packaging material precursor, includes a support; an adhesion layer on one surface of the support; and a barrier layer and a protective layer formed adjacent each other on the adhesion layer. The adhesion layer contains a silicon compound composite. The protective layer is formed of a coating liquid containing a polyvalent metal compound, a polyester resin, and a dispersant, with the polyvalent metal compound being about 40 to about 90 mass % relative to 100 mass %. When the barrier layer is separated from the gas barrier packaging material precursor to measure an infrared absorption spectrum of the barrier layer by a transmission method, a ratio (α/β) of a maximum peak height (α) of absorbance in a range of about 1490 to about 1659 cm−1 to a maximum peak height (β) of absorbance in a range of about 1660 to about 1750 cm−1 is less than about 1.

Abstract: A gas-barrier packaging material including: a support; an adhesive layer laminated on the support; a first barrier layer laminated on the adhesive layer; a second barrier layer laminated on the first barrier layer; and a protective layer formed of a coating liquid that contains a polyvalent metal compound, a polyester based resin, and a dispersant that is a sodium salt of a polycarboxylic acid based resin, the protective layer being laminated on the second barrier layer. In the gas-barrier packaging material, the protective layer contains the polyvalent metal compound by about 40 to 90 wt % relative to 100 wt % of the protective layer. When the second barrier layer is separated and an infrared absorption spectrum of the second barrier layer after separation is measured by a transmission method, a ratio between a maximum peak height α in a range of about 1,490 to about 1,659 cm−1 and a maximum peak height β in a range of about 1,660 to about 1,750 cm−1 as expressed by α/β is less than about one.

Abstract: This coating solution for a gas barrier contains an ammonium salt (A) of a polymer having a carboxyl group, a particulate multivalent metallic compound (B), and water, the content of the multivalent metallic compound (B) being about 0.5-2.0 times the chemical equivalent of the ammonium salt (A), and the mean particle diameter of the multivalent metallic compound (B) being about 4 μm or less.
