Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.

Methods of fabricating glass articles by laser damage and etching

Disclosed are novel light polarizing articles comprising a substrate, a light polarizing layer, an inorganic intermediate layer between the polarizing layer and the substrate, an optional inorganic sub-layer between the substrate and the inorganic intermediate layer, and a protective layer over the light polarizing layer, and method of making the same. Due to the presence of the inorganic intermediate layer and the optional sub-layer, adhesion of the polarizing layer is improved substantially. The light polarizing article has improved chemical, mechanical and thermal resistance. The light polarizing article can be used, for example, as ophthalmic products and in display devices.

Disclosed is a method of preparing a stable composition of radically copolymerizable monomers, said composition containing firstly at least one monomer which has at least one urea function in its formula and secondly at least one monomer which does not have an isocyanate function in its formula, said method comprising preparing said monomer(s) having urea function(s) by reaction of two types of reagent: at least one radically copolymerizable monomer which has at least one isocyanate function in its formula with at least one amine selected from primary and secondary amines, and incorporating said monomer(s) which does(do) not have an isocyanate function in its(their) formula, prior to said reaction, together with one of said reagents, before adding the other of said reagents, and/or during the addition of said reagents, and/or after said reaction. Characteristically, within the context of said method, said reaction for preparing said monomer(s) having urea function(s) is carried out in the absence of non-radically polymerizable solvent, with said reagents, monomer(s) having isocyanate function(s) and amine(s), being incorporated in relative proportions such that the isocyanate equivalent/amine equivalent ratio be between 0.98 and 1.02, and advantageously equal to 1, and said monomer(s) having urea function(s) obtained at the end of said reaction is(are) maintained diluted in the solvent which is constituted of said monomer(s) which does(do) not have an isocyanate function in its(their) formula, in the presence of dissolved oxygen.
