The curable composition is coated onto an MOF. Optionally, the curable composition to is at least partially dried. Next, the curable composition or the at least partially dried curable composition is at least partially cured to provide an abrasion-resistant multilayer optical film. Lastly, the abrasion-resistant multilayer optical film is thermoformed using a female mold having a mold surface.

Abstract: The present disclosure provides a multilayer article. The multilayer article includes a) a microfiltration membrane substrate; b) a first layer directly attached to the first major surface of the microfiltration membrane substrate; and c) a second layer directly attached to the first layer. The first layer includes a first polymeric binder and acid-sintered interconnected first silica nanoparticles arranged to form a continuous three-dimensional porous network. The second layer includes acid-sintered interconnected second silica nanoparticles arranged to form a continuous three-dimensional porous network. The present disclosure also provides a method for forming a multilayer article. The method includes (a) saturating a microfiltration membrane substrate with a liquid; (b) applying a first aqueous coating formulation to at least a portion of a first major surface of the microfiltration membrane substrate to form a coated substrate; (c) sintering the coated substrate, thereby forming a first layer; (d) applying a second aqueous coating formulation to the first major surface of the first layer to form a twice-coated substrate; and (e) sintering the twice-coated substrate.

Abstract: Primer layers for adhesion of pressure sensitive adhesive materials to substrates comprise a cured primer which is the reaction product of an epoxy resin and a polyamine. The epoxy resin may be an aromatic epoxy resin. The polyamine may be a polymer such as polyethylenimine (PEI) or polyvinylamine (PVA). Two-layer constructions comprise the primer layer according to the present disclosure and a substrate layer, which may be directly bound to the primer layer. The substrate layer may comprise one or more polyester polymers, may comprise one or more polymers comprising aromatic groups, and/or may comprise polyethylene terephthalate (PET). Tapes comprise the two-layer construction according to the present disclosure and a pressure sensitive adhesive layer, which may be directly bound to the primer layer. The tape may comprise a second pressure sensitive adhesive layer borne on the opposite face of the tape and optionally a foam layer.
