Abstract
Gas-barrier multilayer structures and gas-barrier shaped articles are sufficiently prevented from clouding even when exposed to cold water at 30° C. or below and have excellent gas barrier properties. Processes for producing such gas-barrier multilayer structures, and coating liquids (A) of excellent coating properties that are used to produce the multilayer structures are also provided. A coating liquid (A) includes a solvent mixture of water and an organic solvent and a polycarboxylic acid polymer partially neutralized with a polyvalent metal wherein the polymer is both dissolved and dispersed as particles in the solvent mixture and wherein the particles dispersed account for 5 to 80 wt% of 100 wt% of the polycarboxylic acid polymer partially neutralized with a polyvalent metal.
