Abstract: The method of the invention comprises: a) forming a hydrophilic polyurethane prepolymer with isocyanate end groups, by the polyaddition reaction of at least one polyol and at least one diisocyanate in the presence of at least one internal emulsifying agent; b) mixing the polyurethane prepolymer with a photochromic agent; c) adding water or a mixture of water and solvent, under agitation, to the mixture of the polyurethane prepolymer and the photochromic agent, to form an emulsion; and d) adding at least one chain extension agent to the emulsion and performing a chain extension reaction to give the final photochromic polyurethane latex. Application to the production of ophthalmic articles having photochromic properties.

Abstract: The method involves preparing a transparent print primer comprising a binder constituted by a colloidal silicon dioxide for increasing diffusion of ink in an aqueous dispersion of polymer, and an absorbing polymer for increasing absorption of ink in the dispersion. The primer is deposited on a face of a plastic substrate of ophthalmic lens for forming a film. The primer is dried and printed using an inkjet printer, and the ink is dried. An independent claim is also included for an ophthalmic lens colored by a coloring method.

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.
