Abstract:
1. A coating material for forming a gas-barrier layer, comprising: a polyalcohol polymer; a polycarboxylic acid polymer, and a divalent or higher-valent metal compound whose surface is coated with a poorly water-soluble component, or alternatively a monovalent metal compound whose surface is coated with a poorly water-soluble component and a divalent or higher-valent metal compound whose surface is coated with a poorly water-soluble component, wherein the mixing ratio between the polyalcohol polymer and the polycarboxylic acid polymer, in terms of the molar ratio (OH group/COOH group) between the OH group and the COOH group, is 0.01 to 20, and the poorly water-soluble component coating the surface of each of the metal compounds is a fatty acid ester organic compound, a phosphoric acid ester organic compound, aluminum hydroxide, or barium sulfate.
