Abstract: Curable ink compositions include a curable aromatic monomer composition, and surface treated metal oxide nanoparticles. The surface treated metal oxide nanoparticles are surface treated with a mixture of at least two silane-functional surface treatment agents, at least one aromatic-containing silane-functional surface treatment agent and at least one silane-functional surface treatment agent comprising a co-polymerizable group. The curable ink composition is inkjet printable, having a viscosity of 30 centipoise or less at a temperature of from room temperature to 60° C., and is free from solvents. The curable ink composition, when printed and cured, has a refractive index of 1.55 or greater, and is optically clear.

Abstract: Layers of siloxane tackifying resins that do not contain siloxane fluids, gums or polymers act as adhesion promotion agents. Articles include a substrate layer, a non-tacky siloxane tackifying resin adhesion promotion layer disposed on the surface of the substrate layer, and a crosslinked siloxane layer in contact with the adhesion promotion layer. The crosslinked siloxane layer is not an adhesive layer. The adhesion of the crosslinked siloxane layer to the substrate is greater than the adhesion without the non-tacky siloxane tackifying adhesion promotion layer.

Abstract: A method of forming a transfer film is described. The transfer film includes a template layer having a first major surface and an opposing second major surface. The second major surface includes a structured non-planar release surface. A backfill layer is disposed upon and conforms to the non-planar structured surface. The backfill layer includes a first cross-linked polymer and a plurality of multifunctional monomers, which cure via different and independent curing mechanisms.
