Patent number: 7687551Abstract: Adhesive compositions useful for laminating cellulosic substrates are formulated using an aqueous emulsion of a vinyl ester polymer such as polyvinyl acetate, one or more monomers or oligomers functionalized with (meth)acrylate groups, and a photoinitiator. The adhesive is cured by drying and exposing the adhesive to UV or visible light and is particularly useful for attaching clear films to cellulosic substrates such as paper and boxboard (e.g., in the manufacture of envelopes or folding cartons having windows).Type: GrantFiled: September 6, 2006Date of Patent: March 30, 2010Assignee: Henkel CorporationInventors: Alexander P. Mgaya, Balasubramaniam Ramalingam
