Publication number: 20180237694Abstract: Disclosed herein is a method for obtaining a material comprising mesogenic compounds forming a liquid crystal mix with a stabilized blue phase. The method includes the steps of a) inducing the liquid crystal mix, contained in a chemical composition, to form the blue phase, then b) illuminating the chemical composition with a light beam of visible wavelength in order to trigger the polymerization of monomers contained in the chemical composition, to obtain the material comprising the liquid crystal mix in the blue phase stabilized by the polymerized monomers. The chemical composition contains a mesogenic system and a chemical photo-initiator system adapted to trigger the polymerization of the monomers when illuminated by the light beam of visible wavelength, in which the mesogenic system includes the mesogenic compounds forming the liquid crystal mix, a chiral dopant adapted to induce the blue phase, and a monomer mix comprising the monomers adapted to polymerize.Type: ApplicationFiled: July 6, 2016Publication date: August 23, 2018Applicant: Essilor InternationalInventors: Samuel ARCHAMBEAU, Jean-Paul CANO, Sevastian GUAZA

Patent number: 9677222Abstract: A selective dyeing method is used for dyeing a substrate, selectively within a first exposed surface portion of said substrate. For this purpose, the substrate consists of a material that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion of the substrate in a second portion of the exposed surface. The substrate is heated such that the dye penetrates a pervious material which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.Type: GrantFiled: March 4, 2015Date of Patent: June 13, 2017Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Samuel Archambeau, Jérôme Ballet, Jean-Paul Cano, Stéphane Perrot
