  The present invention relates to a method for making a substrate coated with a mesoporous photochromic film, comprising: a) preparing a precursor sol of a mesoporous film comprising an inorganic precursor agent, at least one organic solvent, water, at least one pore-forming agent and one hydrophobic precursor agent bearing at least one hydrophobic group; b) depositing a film of the precursor sol onto a main surface of a substrate; c) removing the pore-forming agent from the film resulting from the previous step at a temperature ≦150° C.; d) impregnating the mesoporous film resulting from step c) with a solution comprising at least one photochromic agent. In an alternative embodiment, the photochromic agent is directly introduced into the precursor sol. In an alternative embodiment of the previous alternative embodiment, the precursor sol does not comprise any hydrophobic precursor agent but the photochromic film is made hydrophobic by a treatment subsequent to its preparation.

  本发明涉及一种制备涂有介孔光致变色薄膜的基板的方法，包括：a）制备介孔膜的前体溶胶，该溶胶包括无机前体剂、至少一种有机溶剂、水、至少一种孔形成剂和至少一种带有至少一个疏水基团的疏水前体剂；b）将前体溶胶的薄膜沉积到基板的主表面上；c）在温度≤150℃下从前一步得到的膜中去除孔形成剂；d）用至少一种光致变色剂的溶液浸渍由步骤c）得到的介孔膜。在另一实施例中，光致变色剂直接引入前体溶胶中。在前一种另一实施例中，前体溶胶不包括任何疏水前体剂，但是在其制备后通过处理使光致变色薄膜疏水。

  A polymerizable composition is described, which composition comprises a major amount of a polyol(allyl carbonate) monomer, e.g., diethylene glycol bis(allyl carbonate) monomer, and a minor amount of a radically polymerizable second monomer represented by the general formula, 1 wherein R 2 is a polyvalent linking group that is free of urethane linkages, e.g., R 2 may be a residue of a polyisocyanate, such as isophorone diisocyanate; R 3 is a residue of a material having a single hydroxy group and at least one allyl group, R 3 being free of urethane linkages, e.g., R 3 may be a residue of a poly(alkylene glycol) allyl ether, such as poly(1,2-propylene glycol) allyl ether; and j is a number from 2 to 4. The second monomer may also be present in the composition in an amount at least sufficient such that a polymerizate, e.g., a plus ophthalmic lens, obtained from the composition is substantially free of tinting defects, e.g., ferns and/or moons.
