Abstract

See full text

The present invention relates to an article and a method for its preparation; the article comprises a cured polymeric film superposing paper or paperboard. The polymeric film is derived from a dispersion which comprises:

    a) a dispersant which is a copolymer with an acid value of 130 or less, comprising structural units of ethylene and a carboxylic acid monomer, wherein the copolymer has a melt flow index in the range of from 50 to 2000 g/10 min at 190° C./2.16 kg; wherein the weight-to-weight ratio of structural units of ethylene to carboxylic acid monomer is in the range of from 95:5 to 70:30; and wherein the dispersant has a concentration in the range of from 9 to 50 weight percent based on the weight of polymer solids in the dispersion;b) a base polymer comprising non-functionalized ethylene-co-alkene copolymers, wherein the weight-to-weight ratio of the structural units of ethylene to alkene is in the range of from 99.8:0.2 to 50:50; andc) a neutralizing agent which is a hard base and excludes an organic base having a boiling point of less than 250° C.; wherein the concentration of the neutralizing agent is sufficient to neutralize at least half of the carboxylic acid groups associated with the dispersion composition.
