The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

Articles including nanostructured surfaces and enclosed voids, and methods of making same

Curable compositions include an acrylate of Formula I: Formula I at least one multifunctional (meth)acrylate with fused aromatic groups, heteroarylene groups, heteroalkylene groups, alkylene groups, or aralkylene groups, and a photoinitiator. The compositions, when cured, have a refractive index of 1.63 or greater at 532 nanometers, are optically transparent, and have a thermal stability such that upon heating for 1 hour at 250&#xb0; C. they have a weight loss of 3.5% or less.

Curable high refractive index compositions and articles prepared from them

Curable ink compositions include at least one aromatic (meth)acrylate, at least one multifunctional (meth)acrylate with heteroaromatic groups, fused aromatic groups, heteroalkylene groups, or a group containing both heteroalkylene and aromatic groups, and a photoinitiator. The curable ink composition is Inkjet printable, having a viscosity of 30 centipoise or less at a temperature of from room temperature to 35&#xb0; C., and is free from solvents. The ink composition, when printed and cured has a refractive index of 1.55 or greater, and is optically clear. The cured ink composition, when cured to a thickness of from 1-16 micrometers, has a surface roughness of less than or equal to 5 nanometers.
