Abstract: A method of curing a coating includes forming a primer coating from a composition for use in a conductive nanoparticle composition, wherein the composition comprises a multifunctional acrylate oligomer; an acrylate monomer; a photoinitiator; and a solvent; wherein the primer composition includes a total weight, wherein 5% to 20% of the total weight comprises the multifunctional acrylate oligomer, wherein 15% to 20% of the total weight comprises the acrylate monomer, wherein 1.5% to 6% of the total weight comprises the photoinitiator; and wherein 50 to 78% of the total weight comprises the solvent; applying the primer coating to a surface of a substrate to form a coated substrate; applying irradiation to the primer coating with an ultraviolet light lamp having a peak irradiance of at least 1500 milliWatts; and curing the coating.

Abstract: In one embodiment, a graphic image display can comprise: a backlight source; a light transmitting first sheet having a viewing side and a backside, with a plurality of geometric microstructure units on the backside; and a second layer comprising a source of graphic image information. The plurality of geometric microstructure units can be selected from microlenses, polyhedral shapes, lenticular shapes, and combinations comprising at least one of the foregoing. The graphic image display can be suitable for viewing under ambient light from the viewing side alone, under backlighting alone, and in the presence of both ambient light from the viewing side and backlighting.

Abstract: A method of making a polyurethane coating can comprise: mixing an unblocked isocyanate component with a polyol component in the presence of a hydroxyl-free solvent and a catalyst to form a reaction mixture; depositing the reaction mixture onto a polymer substrate; and curing the reaction mixture on the substrate to form a polyurethane coated substrate. The polyurethane coated substrate can have a percent thinning of greater than or equal to 10%, e.g., without cracking or delamination when measured on a rectangular block having 90° angles.
