| titleOfInvention | Optical article comprising a temporary antifog coating based on sorbitan surfactants |
| abstract | 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: —(R d O) z —(Y) n2 —R′, in which R d 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 1 9, preferably 1 3 to 19 carbon atoms. Surfactants A provide a visual indication whether or not the antifogging effect will still be long-lasting. |
