Patent ID: 7105207

Claim:
A process for preparing a flexible film laminate, comprising; a. applying a liquid, UV curable, oligomeric, adhesive composition comprising the reaction product of, i. an acrylate terminated oligomer having a weight average molecular weight from about 2,000 to about 10,000, and ii. one or more Michael addition donors selected from the group consisting of methyl acetoacetate, ethyl acetoacetate, a malonic ester, 1-3-pendanedione, 1,4-butanediol diacetoacetate, ethoxylated bisphenol A diacetoacetate, trimethylol propane triacetoacetate, polycaprolactone triacetoacetate, and pentaerythritol tetraacetoacetate, where the liquid, UV curable, oligomeric, adhesive composition is a liquid at room temperature and does not contain a photoinitiator, to the surface of at least one layer of a flexible film, b. forming the laminate by contacting the surface of the adhesive bearing surface flexible film with the surface of a second flexible film, and c. curing the liquid, UV curable, oligomeric, adhesive composition by application of UV radiation either immediately after the application of the adhesive to at least one flexible film layer but prior to forming the laminate or by curing after the laminate has been formed.
