COATING LIQUID AND GAS BARRIER LAMINATE

摘要

An object of the invention is to provide aqueous coating liquids that contain ultrafine inorganic compound particles with good dispersibility, and to provide gas barrier laminates of excellent transparency and gas barrier properties that have a layer formed from the coating liquid. A coating liquid of the invention includes ultrafine inorganic compound particles, a polyester resin, a sodium polycarboxylate and water. A gas barrier laminate of the invention includes a substrate and a gas barrier layer formed on the substrate, wherein the gas barrier layer has a layer (A) formed from the coating liquid and a layer (B) containing a polycarboxylic acid polymer.
