Abstract: The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, a (meth)acrylate monomer, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPA·s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88%, and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.

Abstract: An optically clear adhesive composition is provided that is derived from precursors that include from about 0 to about 50 parts by weight of an alkyl acrylate having 1-11 carbon atoms in the alkyl group, from about 40 to about 95 parts by weight of an alkyl acrylate having 12 or more carbon atoms in the alkyl group, from about 5 to about 20 parts by weight of a copolymerizable polar monomer, and an initiator. The adhesive composition has a moisture content of less than about 1.0% when the adhesive is positioned in between two release films and placed in an environment of 85 C/85% relative humidity for 72 hours and then cooled down to room temperature. Moreover, when the adhesive composition is placed between two transparent substrates and made into a laminate, the laminate has a haze value of less than about 5% after the laminate is placed in an environment of 85 C/85% relative humidity for 72 hours and then cooled down to room temperature.

Abstract: The present disclosure provides a crosslinkable composition including a (meth)acrylate polymer and a visible light absorbing compound. Two percent or less of the carbon-carbon bonds in the crosslinkable composition are double bonds. The composition allows for inclusion of one or more materials degradable by ultraviolet radiation and/or stabilized against ultraviolet radiation. Methods for making a crosslinked composition is also provided. One method includes obtaining a crosslinkable composition and subjecting the crosslinkable composition to radiation having a wavelength of 400 nm or greater. Another method includes subjecting a crosslinkable composition to first and second radiations that are different from each other.

Abstract: Processing tapes have special properties to permit them to be used to prepare laminate articles, such as security articles. The processing tapes include a backing, a pressure sensitive adhesive layer and a release surface covering the pressure sensitive adhesive layer. The backing is a dimensionally stable transparent polymeric film, and the surface on which the pressure sensitive is coated may be a treated surface. The pressure sensitive adhesive is a transparent pressure sensitive adhesive that includes a crosslinked (meth)acrylate-based polymer and has a refractive index in the range of 1.45-1.55. The (meth)acrylate-based polymer includes alkyl (meth)acrylate monomers and may include acidic monomers.

Abstract: There is provided a pressure sensitive adhesive composition comprising a polyurethane polymer that comprises the reaction product of a polyisocyanate component and a polyol component. The polyol component has a hydrophilic-lipophilic balance (HLB) less than 10. The polyurethane further comprises 0.5 to 10 wt.-% of hydrophilic polymerized units having an HLB greater than 12, such as a reaction product of a polyethylene glycol polymer. In another embodiment, the polyurethane further comprises pendent ethylenically unsaturated groups. Also described are articles such as laminating tapes and protective films as well as methods of bonding substrates with the pressure sensitive adhesive and laminating tape.
