Gas barrier laminates, coating liquids for their production, packaging materials, packaging bodies and packaging articles

摘要

PROBLEM TO BE SOLVED: To achieve high gas barrier property without strict control for preventing mixing of water. A coating liquid for producing a gas barrier laminate of the present invention contains a carboxy group-containing polymer (A), polyvalent metal-containing particles (B), a surfactant (C), and an organic solvent (D). The number average molecular weight of the carboxy group-containing polymer (A) is 100,000 or less. [Selection diagram] None
