  • Patent number: 9006338
    Abstract: An aqueous resin composition with gas barrier properties contains (i) polyurethane resin having aurethane group and a urea group in a total concentration of 25 to 60% by weight and having a acid value of 5 to 100 mgKOH/g, (ii) a swelling inorganic layered compound (e.g., a water-swelling mica, and a montmorillonite), and (iii) a polyamine compound having an amine value of 100 to 1900 mgKOH/g. The polyurethane resin (i) is obtained by a reaction of (A) an aromatic, araliphatic or alicyclic polyisocyanate, (B) a polyhydroxyalkanecarboxylic acid, and at least one component selected from (C) a C2-8alkylene glycol and (D) a chain-extension agent (e.g., diamine, hydrazine and a hydrazine derivative), and neutralized with a neutralizing agent. The proportion of the acid group of the polyurethane resin (i) relative to the basic nitrogen atom of the polyamine compound (iii) is 10/1 to 1/5 as the equivalent ratio.
