    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.
