Patent number: 9494713Abstract: An optical article includes a substrate having a main surface coated with an antireflection coating and, directly contacting the antireflection coating, a precursor coating of an antifog coating obtained through the grafting on the antireflection coating of at least one compound B bearing a polyoxyalkylene group, the coating precursor of the antifog coating being coated with a surfactant film so as to form an antifog coating. The surfactant film contains at least one surfactant A having a sorbitan ring hydroxyl groups functionalized with OH-terminated polyoxyalkylene groups and R1 groups of formula:—(RdO)z—(Y)n2—R?, in which Rd is an alkylene group, z is an integer >1, Y is a divalent group, n2 is 0 or 1 and R? is a saturated hydrocarbon group having 12 to 19, preferably 13 to 19 carbon atoms. Surfactants A provide a visual indication whether or not the antifogging effect will still be long-lasting.Type: GrantFiled: October 14, 2011Date of Patent: November 15, 2016Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Annette Cretier, Charlotte Saint-Lu
