摘要： The invention relates to an optical article comprising a substrate coated with an abrasion and scratch resistant coating composed of a lower layer and an upper layer that do adhere to each other, the upper layer and the lower layer being layers of cured upper and lower layer compositions, said upper layer composition comprising at least one organosilane, or a hydrolyzate thereof, of formula RnYmSi(X)4-n-m and at least one compound, or a hydrolyzate thereof, of formula M(Z)x, the following ratio being lower than 2.3: Rs = theoretical dry matter weight of compounds I in the upper layer composition theoretical dry matter weight of compounds II in the upper layer composition said lower layer composition comprising at least one organosilane, or a hydrolyzate thereof, of formula R′n′Y′m′Si(X′)4-n′-m′ and, optionally, at least one compound, or a hydrolyzate thereof, of formula M′(Z′)y, the following ratio being higher than 2.3: Ri = theoretical dry matter weight of compounds III in the lower layer composition theoretical dry matter extract of compounds IV in the lower layer composition In the hereabove formulas, M and M′ are metals or metalloids of valences x and y, at least equal to 4, R and R′ groups are monovalent organic groups that are bound to silicon through a carbon atom and that contain at least one epoxy function, X, X′, Z and Z′ groups are hydrolyzable groups, Y and Y′ are monovalent organic groups that are bound to silicon through a carbon atom, n, m, n′ and m′ being integers such that n and n′=1 or 2 with n+m and n′+m′=1 or 2.

摘要： The present invention relates to an electrochromic composition comprising at least one reducing compound, at least one oxidizing compound which is selected from specific viologen derivatives, and at least one dye. Said composition can be used as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

摘要： The present invention relates to a group of novel electrochromic materials. More specifically, it relates to electrochromic materials having two-core viologens and the use of these two-core viologens as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

摘要： The present invention relates to a group of novel electrochromic materials. More specifically, it relates to electrochromic materials based on either single or two-core viologen systems and the use of these viologen systems as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.
