  The present invention relates to an optical article comprising a substrate having at least one main surface coated with a coating comprising at least one layer of an abrasion and/or scratch-resistant coating, wherein the abrasion and/or scratch-resistant coating is formed from a composition comprising at least one epoxy compound bearing at least one silicon atom having at least one hydrolysable group directly linked to the silicon atom and at least one group comprising an epoxy function linked to the silicon atom through a carbon atom, and/or a hydrolysate thereof, at least one plasticizer, a silane hydrolysate and colloidal silica, wherein the total amount of plasticizer in the composition is lower than 10wt% of the dry extract of the total composition, and wherein the weight ratio of silane of formula (I) to plasticizer is higher than 0.4 in the dry exact of the composition. The invention further relates to a process for the manufacture of such an abrasion and/or scratch-resistant coating on a substrate.

  本发明涉及一种光学制品，该光学制品包括基底，该基底至少有一个主表面涂有一层涂层，该涂层包括至少一层耐磨和/或抗划伤涂层，其中耐磨和/或抗划伤涂层由一种组合物形成，该组合物包括至少一种环氧化合物，该环氧化合物含有至少一个硅原子，该硅原子上有至少一个与硅原子直接相连的可水解基团和至少一个通过碳原子与硅原子相连的环氧官能团、和/或其水解物、至少一种增塑剂、硅烷水解物和胶体二氧化硅，其中组合物中增塑剂的总量低于总组合物干萃取物的 10wt%，式（I）硅烷与增塑剂的重量比高于组合物干萃取物的 0.4。本发明进一步涉及在基材上制造这种耐磨和/或抗划伤涂层的工艺。
