Patent application numberDescriptionPublished
20090146104ALIGNMENT FACILITIES FOR OPTICAL DYES - Various non-limiting embodiments disclosed herein provide phase-separating polymer systems including a cured polymeric liquid crystal matrix phase and a guest phase including at least one photoactive material where the guest phase separates from the matrix phase during the curing process. Optical elements, including ophthalmic elements and other articles of manufacture including the phase-separating polymer systems are also disclosed. Methods of forming a liquid crystal phase-separating photoactive polymer system are also described.06-11-2009
20100014010FORMULATIONS COMPRISING MESOGEN CONTAINING COMPOUNDS - Compounds including at least one mesogenic substructure and at least one long flexible segment and methods of synthesizing the same are disclosed. Formulations which include various embodiments of the mesogen containing compounds and their use in articles of manufacture and ophthalmic devices are also disclosed.01-21-2010
20110128457ALIGNMENT FACILITIES FOR OPTICAL DYES - Provided are phase-separating polymer systems including a cured polymeric liquid crystal matrix phase and a guest phase including at least one photoactive material where the guest phase separates from the matrix phase during the curing process. Optical elements, including ophthalmic elements and other articles of manufacture including the phase-separating polymer systems are also disclosed. Methods of forming a liquid crystal phase-separating photoactive polymer system are also described.06-02-2011
20110279883POLARIZING PHOTOCHROMIC ARTICLES - Provided are photochromic articles that include a substrate, a primer layer that includes a first photochromic compound, and a photochromic-dichroic layer over the primer layer that includes a photochromic-dichroic compound. The first photochromic compound and the photochromic-dichroic compound each are selected such that the photochromic-dichroic compound has an absorbance of less than or equal to 0.1 at the wavelength of peak absorbance of the underlying first photochromic compound. The present invention also relates to such photochromic articles that further include a topcoat layer over the photochromic-dichroic layer. The topcoat layer can include a second photochromic compound that has an absorbance of less than 0.1 at the wavelength of peak absorbance of the underlying photochromic-dichroic compound. The photochromic articles provide, for example, a combination of linear polarizing properties, and reduced percent transmittance when in a colored or darkened state, such as when exposed to actinic light.11-17-2011
