intermediate barrier layer.

A barrier material polymeric thermoset obtainable by reacting: (i) an amino-functional polymeric resin gelling each, which is a reaction product of a polyamine and a polyfunctional material selected from polyepoxides, polyacrylates and polyoxalates having at least two groups said polyamine functional reactive further characterized in functional amino ungelled resin containing an average of m as two portions separated by polyamine molecule within said resin; and (ii) a polyepoxide having a 1,2-epoxy equivalency greater than 1.0; containing said thermosetting polymeric material barrier at least seven percent by weight amine nitrogen, based on the total weight of components (i) and (ii).
