| 20080252846 | Polarizing Ophthalmic Lens Adapted to a Wearer's Eye/Head Behavior - The invention relates to a method for producing a polarising ophthalmic lens adapted to the eye/head behaviour of the wearer thereof and to said lens. The inventive ophthalmic lens comprises several areas associated to differently oriented polarising filters. The size and position of at least certain areas are determined according to the lens wearer's eye/head behaviour. | 10-16-2008 |

| 20110033802 | METHOD FOR PREPARING A PHOTO-CROSSLINKABLE COMPOSITION - The invention relates to a photo-crosslinkable composition that can be obtained by a method including the following steps: (a) the hydrolysis and condensation reaction of a [(epoxycycloalkyl)alkyl]thalkoxysilane in solution in an organo-aqueous medium containing water in an initial water/monomer molar ratio of between 3 and 15, with at least one water-soluble solvent, at a pH of between 1.6 and 4.0, by heating the solution to a temperature of between 50 and 70° C. for a duration of between 180 and 350 minutes in order to obtain a solution of an organo-mineral hybrid prepolymer, in which the totality or quasi-totality of the alkoxysilane groups has been hydrolysed, and which comprises in average at least 4 (epoxycycloalkyl)alkyl groups; (b) cooling the polyepoxide prepolymer composition thus obtained down to a temperature of between 15 and 25° C.; (c) adding to said composition at least one cationic-polymerisation photo-primer and at least one photosensitiser having a maximum absorption at a wavelength of between 300 and 420 nm, and optionally adding a surfactant; (d) agitating the composition thus obtained for a duration of between 10 and 120 minutes at a temperature of between 15 and 25° C.; (e) filtering the composition thus obtained with a filter comprising pores with an average size of between 1 and 5 μm; and (f) storing the liquid filtrate thus obtained at a temperature lower than 0° C., preferably between −20 and −10° C. The invention also relates to the use of such a photocrosslinkable composition as a negative photosensitive resin in a photolithography process. | 02-10-2011 |
| 20110070361 | NON-ELECTROLYTIC DEPOSITION METHOD - The invention relates to a method for the non-electrolytic deposition of a compound, preferably an electrochromic compound, comprising the following successive steps: (a) an electroconductive layer is deposited on a non-conductive solid substrate; (b) a reducing agent or an oxidizing agent (=redox agent) is deposited on an area of said electroconductive layer, said area covering only a portion of the surface of said electroconductive layer; and (c) a solution of a precursor of the compound to be deposited is brought into contact both with the redox agent and with at least a portion of the area of said electroconductive layer not covered by the redox agent, said precursor being chosen from those having an oxidation-reduction potential higher or lower than the redox agent and forming, after an oxidation-reduction reaction, a compound insoluble in the solution of the precursor of the compound to be deposited. | 03-24-2011 |
| 20110211245 | TRANSPARENT ELECTROACTIVE SYSTEM - The invention relates to a transparent electroactive system that includes two electrodes ( | 09-01-2011 |
