  • Patent number: 8637226
    Abstract: A method of forming an image having multiple phases is disclosed herein. The method includes forming exposed and unexposed areas, the exposed areas comprising a first polymer network exhibiting first and second phases that are chemically connected and have different refractive indices, the first phase being continuous, and the second phase comprising a plurality of structures dispersed within the first phase, and the unexposed areas comprising a second polymer network comprising third and fourth phases that are chemically connected and have different refractive indices, the third phase being continuous, and the fourth phase comprising a plurality of structures dispersed within the third phase. The first and second polymer networks are chemically connected, and morphology formed by the first and second phases is different than that formed by the third and fourth phases.

  • Patent number: 8611010
    Abstract: A method of reducing optical fringing of a coated substrate is described. The method comprises providing a (e.g. light transmissive) substrate; providing a primer having an unmatched refractive index, and applying the primer to the substrate forming a primer layer having an optically significant thickness. The primer layer in combination with the substrate has a percent reflectance at a maximum at a wavelength of interest. Also described are articles comprising a substrate, a primer having an unmatched refractive index, a high refractive index layer, and optional low refractive index layer such as an antireflective film article.

  • Patent number: 8470439
    Abstract: Antireflective films are described having a surface layer comprising a the reaction product of a polymerizable low refractive index composition comprising at least one free-radically polymerizable fluoropolymer and surface modified inorganic nanoparticles. A high refractive index layer is coupled to the low refractive index layer. In one embodiment, the high refractive index layer comprises surface modified inorganic nanoparticles dispersed in a crosslinked organic material. The antireflective film is preferably durable, exhibiting a haze of less than 1.0% after 25 wipes with steel wool using a 3.2 cm mandrel and a mass of 1000 grams.

  • Patent number: 7510741
    Abstract: Methods of making an optical body include coating a mixture including a first cholesteric liquid crystal polymer, a second cholesteric liquid crystal monomer, a second cholesteric liquid crystal polymer formed from a portion of the second cholesteric liquid crystal monomer, and a solvent on a substrate. The first cholesteric liquid crystal polymer is different than the second cholesteric liquid crystal polymer. Then, forming from the mixture an optical body including a first layer, a second layer, and a third layer disposed between the first and second layer. The first layer includes a majority of the first cholesteric liquid crystal polymer. The second layer includes a majority of a second cholesteric liquid crystal monomer. The third layer includes the second cholesteric liquid crystal polymer.
