Abstract: A pressure-sensitive adhesive is provided that is a dried product of a latex composition, which is formed from an emulsion composition. The latex composition and the emulsion composition are also provided. The emulsion composition has droplets that contain various monomers plus a (meth)acrylate polymer and a hydrogenated hydrocarbon tackifier dissolved in the monomers. Additionally, an article containing a layer of the pressure-sensitive adhesive and a method of forming the pressure-sensitive adhesive are provided. The pressure-sensitive adhesives often have both high peel adhesion and high shear strength (i.e., high cohesive strength or high shear holding power).

Abstract: Methods for producing an at least partially cured layer by applying a layer including a (meth)acrylate-functional siloxane to a surface of a substrate, and irradiating the layer in a substantially inert atmosphere with a short wavelength polychromatic ultraviolet light source having a peak intensity at a wavelength of from about 160 nanometers to about 240 nanometers to at least partially cure the layer. Optionally, the layer is at a curing temperature greater than 25° C. In some embodiments, the layer has a thickness of about 0.1 micrometers to about 1 micrometer. In certain embodiments, the layer is substantially free of a photoinitiator and/or an organic solvent. In some particular embodiments, irradiating the layer with a short wavelength polychromatic ultraviolet light source takes place in an inert atmosphere including no greater than 50 ppm oxygen. The substantially cured layer may be a release layer or a low adhesion backsize (LAB).
