The present disclosure relates to micro-optical assemblies containing at least one optical element adhered to a receptor substrate, e.g. a transparent receptor substrate, the receptor substrate contains at least one graphics layer. The micro-optical assemblies include both functional micro-optical structures that can alter, for example, incident light, and a graphic layer, which includes at least one graphic, e.g. a graphic design, which may include color, patterns, imagery, indicia and the like. The combination of the micro-optical elements with the graphic of the graphics layer can provide unique light altering assemblies that have graphic designs that may be functional, e.g. to display a message, and/or have aesthetic value. The micro-optical assemblies of the present disclosure are useful in a variety of applications which include, but are not limited to, display and graphics applications and architectural glass applications. The present disclosure also provides a method of making the micro-optical assemblies of the present disclosure.

Curable, coatable compositions include silane surface-treated inorganic nanoparticles with a high refractive index, and a curable reaction mixture. The curable reaction mixture includes a first (meth)acrylate monomer comprising a high refractive index (meth)acrylate monomer with a refractive index of 1.6 or higher, a second (meth)acrylate monomer comprising a lower refractive index (meth)acrylate monomer with a refractive index of less than 1.6, and at least one initiator. Cured optical coatings prepared from the compositions are optically clear, having a visible light transmission of at least 88% and a haze of 5% or less, and have a refractive index of at least 1.78, and are capable of passing a 10 millimeter mandrel flexibility test.

A nanostructured article having a first layer with a nanostructured surface is described. The nanostructured surface includes a plurality of pillars extending from a base surface of the first layer. The pillars have an average height greater than an average lateral dimension of the pillars. An average center-to-center spacing between pillars is no more than 2000 nm. The average lateral dimension is no less than 50 nm. Each pillar in the plurality of pillars has at least a lower portion and an upper portion where the lower portion is between the upper portion and the base surface, and the upper and lower portions have differing compositions. The nanostructured article includes a second layer disposed over the plurality of pillars and extending continuously to the base surface.
