Abstract: Various embodiments disclosed related to flexible fibrous surface-treating articles with low formaldehyde off-gassing. In various embodiments, the present invention provides a flexible fibrous surface-treating article including an open, lofty, nonwoven web including fibers. The flexible fibrous surface-treating article also includes a binder that coats the fibers of the nonwoven web. The binder includes a cured product of a curable composition including a latex and a crosslinker. The flexible fibrous surface-treating article heated to 65° C. in a closed space for 30 minutes emits less than about 6 micrograms of gaseous formaldehyde total per gram of the flexible fibrous surface-treating article.

Abstract: Low loss, high reflectivity wide band mirror films provide a desired mix of specular reflection and diffuse reflection or scattering to provide semi-specular reflectivity. The mirror films generally include both a specularly reflective multilayer optical film (MOF) having a wide reflection band, and a scattering layer. In some cases a low refractive index TIR layer is sandwiched between the MOF and the scattering layer. In other cases the scattering layer contacts the MOF directly. In embodiments that include the TIR layer, the TIR layer preferably has a nanovoided morphology and includes a plurality of particles and a polymer binder. In embodiments wherein the scattering layer contacts the MOF directly, the scattering layer preferably also has a nanovoided morphology and includes a plurality of particles and a polymer binder.

Abstract: Hot melt processable composition mixtures include an acid-functional (meth)acrylate-based adhesive composition and a zinc di-(meth)acrylate salt. The adhesive composition has a hot melt processing temperature, and the zinc salt has a melting point that is higher than the hot melt processing temperature of the adhesive composition. The mixture is hot melt processable, and upon application to a substrate, the mixture forms an ionically crosslinked layer with thermally reversable ionic crosslinks.
