Abstract: A gas barrier laminate in which separation between a coating layer having gas barrier properties and a layer adjacent to the coating layer is less likely to occur. A coating solution for producing a gas barrier laminate contains a carboxyl group-containing polymer (A), polyvalent metal-containing particles (B), a surfactant (C), an organic solvent (D), and at least one silicon-containing compound (E) selected from the group consisting of a silane coupling agent represented by the following general formula (1), a silane coupling agent represented by the following general formula (2), hydrolysates thereof, and condensates thereof, wherein the mass ratio of the silicon-containing compound (E) to the carboxyl group-containing polymer (A) is 0.5% or more. Si(OR1)3Z1 . . . (1); Si(R2)(OR3)2Z2 . . . (2). (R1 and R3 are alkyl groups having 1 to 6 carbon atoms, R2 is a methyl group, and Z1 and Z2 are a group containing an epoxy group.)

Abstract: High gas barrier properties can be achieved without requiring strict control for preventing entry of moisture. A coating liquid for producing a gas barrier laminate contains a carboxy group-containing polymer, polyvalent metal-containing particles, a surfactant, and an organic solvent. In the coating liquid, the carboxy group-containing polymer has a number average molecular weight of 100,000 or less.

Abstract: Deterioration of gas barrier properties due to sedimentation of aggregates in a coating liquid is decreased or minimized. A coating liquid for producing a gas barrier laminate contains a carboxy group-containing polymer, polyvalent metal-containing particles, a high molecular weight dispersant with an acidic group, and an organic solvent, and has a pH in a range of 4 to 6 at 25° C.
