Abstract: [Problems] To provide a coating composition for undercoating which, in forming a gas-barrier layer having a crosslinked structure between a polycarboxylic acid type polymer and polyvalent metal ions by the heating at a low temperature for a short period of time, permits polyvalent metal ions to be easily and quickly fed into the polycarboxylic acid type polymer and, besides, into the whole gas-barrier layer. [Means for Solution] A coating composition containing, as chief components, a nonaqueous polyester polyol, an isocyanate compound, and an alkaline compound of a polyvalent metal that serves as an ion source for forming the crosslinked structure, wherein (a) the nonaqueous polyester polyol contains a nonaqueous polyester polyol which contains a metal element in the resin skeleton thereof as an essential component, and (b) the alkaline compound of the polyvalent metal has an average primary particle size in a range of 0.005 to 0.5 u m.

Abstract: The present invention provides a gas barrier layered product exhibiting a high oxygen barrier property independent of humidity and having excellent transparency, and a method of manufacturing the same. The gas barrier layered product includes a base material and a layer stacked on the base material. The layer is formed of a composition includes: a hydrolyzed and condensed product of a compound (L) containing a metal atom to which at least one group selected from a halogen atom and an alkoxy group is bonded; a neutralized product of a polymer containing a functional group selected from a carboxyl group and a carboxylic anhydride group; and a compound (D). At least a part of a -COO- group contained in the at least one functional group is neutralized by a metal ion having a valence of two or more. The compound (L) includes at least one compound (A) in which an organic group having at least one characteristic group, selected from a halogen atom, a mercapto group and a hydroxyl group, further bonded to the metal atom. The compound (D) is a compound bonding to both the -COO- group of the neutralized product of the polymer and a group on the surface of the hydrolyzed and condensed product.

Abstract: Disclosed is a method for improving the barrier properties of polyethylene films. The method comprises mixing a substantially linear, high density polyethylene with a nucleating agent and converting the mixture into a film. The film made by the method of the invention has at least a 15% improvement on the water vapor barrier property and/or in the oxygen barrier property compared with the control film made from the same substantially linear, high density polyethylene but does not contain the nucleating agent.
