Abstract: Procédé d'obtention d'un latex photochromique comprenant: (1) la préparation d'un mélange comprenant au moins un monomère organique Z à groupement C=C, polymérisable par voie radicalaire, au moins un composé photochromique organique, au moins un agent tensio-actif, de l'eau et éventuellement un amorceur de polymérisation; (2) le traitement du mélange obtenu à l'étape (1) pour former une miniémulsion comprenant une phase organique dispersée sous forme de gouttelettes ayant un diamètre de 50 à 500 nm, de préférence 50 à 300 nm, dans une phase aqueuse; (3) l'addition à la miniémulsion d'un amorceur de polymérisation, si celui-ci n'a pas été introduit lors de l'étape (1), ou d'une quantité supplémentaire d'amorceur par rapport à l'étape (1); (4) la polymérisation du mélange réactionnel obtenu à l'étape (3), et (5) la récupération du latex photochromique. La formation de films photochromiques est également décrite.

Abstract: The invention relates to methods for obtaining the photochromic latex comprising the polymerization in aqueous emulsion of an initial polymerizable mixture, comprising one or more monomers polymerizable by free-radical mechanism and one or more photochromic compounds and the addition to the initial polymerizable mixture, during the polymerization of the initial polymerizable mixture or to the final latex of at least one agent for stabilizing the photochromic properties. Such latexes can be used in the production of photochromic films. Such films may be used, for example, on optical lenses.

Abstract: Impregnation of polymer latex particles with an additive (I) involves contacting (I) with the latex in presence of fluid (II) under supercritical pressure, in which (I) is soluble, for sufficient time to carry out the impregnation. An Independent claim is included for a latex comprising polymer particles impregnated with (I).

Abstract: The lens has zones (2a, 2c) associated to polarizing filters, where the size and position of the zones are determined based on an eye/head behavior of a wearer e.g. driver, along different orientations. The polarizing filter of one of the zones is oriented vertically with respect to a usage position of the lens that is utilized in a glass (2), where the vertical zone is situated adjacent to a temporal lateral edge of the lens with respect to the usage position.
