摘要:
The present invention includes optical coatings containing ultraviolet curable monomers employing a bromine substituted fluorene structure. The fluorene backbone of the monomers of the present invention may also be functionalized with one or more polymerizable or reactive functionalities, and most readily at the 9 position. Compositions of the present invention include the reactive bromosubstituted fluorenes combined with inorganic nanoparticles, particularly nanoparticles with reactive surface modifiers exhibiting polymerizable functionality. Reactive high index nanoparticles such as surface modified zirconia are contemplated.
摘要:
The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modification of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.
摘要:
Presently described are coating compositions comprising a polymerizable resin composition and a non-ionic unpolymerizable surfactant. In some embodiments, the coating comprises greater than 10 wt-% of non-ionic unpolymerizable surfactant. In other embodiments, the coating composition comprises an an additive comprising a silicone group or a fluorinated group and a hydrophobic group. Also described are articles comprising the cured coating compositions. In one embodiment, an article is described comprising a cured coating wherein the cured coating exhibits a property of an initially visible simulated fingerprint reducing in visibility in 1-20 minutes. Also described is a method of determining the fingerprint visibility of a coating composition and a polyacylate composition useful as an additive. In another embodiment a coated surface is described comprising a polymeric organic material comprising a plurality of pores wherein a portion of the pores are interconnected and comprise a lipophilic liquid.

Optical films are described comprising a color shifting film comprising a matte surface layer; and light control microstructured layer disposed proximate the color shifting film. The optical film may comprise a matte layer disposed on a major surface of the color shifting film and the light control micro structured layer disposed on the color shifting film at an interface that is free of adhesive. Alternatively, the optical film may comprise a film stack comprising a light control film having a light control microstructured layer, a color shifting film, and an adhesive layer between the light control film and color shifting film. In some embodiments, the matte layer comprises matte particles. In other embodiments, the matte layer comprises a plurality of microstructures and no greater than 50% of the microstructures comprise embedded matte particles. In some embodiments, the microstructures are substantially free of embedded matte particles.
