Abstract: Le procédé d'obtention de latex photochromique comprend la polymérisation en émulsion aqueuse d'un mélange polymérisable initial, comprenant un ou plusieurs monomère(s) polymérisable(s) par voie radicalaire et un ou plusieurs composé(s) photochromique(s) et l'addition au mélange initial, au cours de la polymérisation ou au latex final d'au moins un agent de stabilisation des propriétés photochromiques choisis parmi les composés du cyclopentène, du cyclohexène, du cycloheptène, du cyclooctène et les composés à insaturation éthyléniques, comportant, en position a par rapport à l'insaturation éthylénique, un atome de carbone portant un groupe hydroxy libre. Application à la fabrication de films photochromiques est également décrite.

Abstract: The invention is dedicated to a colored latex comprising a mixture of an uncolored initial latex and at least one initial aqueous dispersion of at least one pigment being under the form of particles, wherein the particles of the pigment(s) are water-insoluble, and an amount of at least 90% of the particles of the one or more pigment(s) have a particle size of 370 nm or less, in the initial aqueous dispersion. The invention also relates to a process for preparing such colored latex and an ophthalmic lens coated with a layer of such colored latex.

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.
