Water Dispersion And Laminate

Abstract: This aqueous dispersion contains a resin component and water. The resin component contains an ethylene-unsaturated carboxylic acid copolymer. The ethylene-unsaturated carboxylic acid copolymer includes a first ethylene-unsaturated carboxylic acid copolymer, a second ethylene-unsaturated carboxylic acid copolymer and a third ethylene-unsaturated carboxylic acid copolymer, which have different carboxyl group content ratios from one another. The difference (C - B) between the carboxyl group content ratio C of the third ethylene-unsaturated carboxylic acid copolymer and the carboxyl group content ratio B of the second ethylene-unsaturated carboxylic acid copolymer, and the difference (B - A) between the carboxyl group content ratio B of the second ethylene-unsaturated carboxylic acid copolymer and the carboxyl group content ratio A of the first ethylene-unsaturated carboxylic acid copolymer are within a specific range.
