An article includes a glass substrate including two main faces defining two main surfaces separated by edges and a temporary protective layer comprising an organic polymer matrix deposited on at least one portion of a main surface of the glass substrate, wherein the temporary protective layer has a rough surface defined by a surface roughness parameter Sa, corresponding to the arithmetic mean height of the profile of the surface, of greater than 0.2 &#x3bc;m.

Item protected by a rough temporary protective cover

The present invention relates to an article comprising at least one glass-ceramic substrate, in particular a plate, intended, for example, to cover or receive at least one heating element, said substrate exhibiting, in at least one zone, a surface roughness such that the characteristic dimensions of the patterns forming said roughness are between 2 and 100 &#x3bc;m. The present invention also relates to an advantageous process for producing said substrate.

Glass-ceramic article and manufacturing process

An article includes a glass substrate comprising two main faces defining two main surfaces separated by edges, the substrate bearing a functional coating deposited on at least one portion of a main surface and a temporary protective layer deposited on at least one portion of the functional coating having a thickness of at least 1 micrometer, wherein the temporary protective layer includes an organic polymer matrix and infrared-absorbing materials.

A vehicle glazing includes on its surface to be exposed to the exterior atmosphere, at least in a zone not wiped by the windscreen wipers, a mineral oxide layer of 0.1 to 20 &#x3bc;m thickness, 30 to 90% of the volume of which consists of 20 to 300 nm open pores that are distributed uniformly throughout the thickness of the layer, and almost all of which are connected to one another, the internal and external surface of the layer being functionalized with a compound containing a perfluoroalkyl or alkyl functional group, then saturated with a hydrophobic oil that impregnates the functionalized porous layer and forms a film on the surface thereof, the at least one zone being located facing a detecting device such as an anti-collision/obstacle-detecting/security video camera, or similar, placed in the interior of the vehicle, in particular on the face of the glazing.

A transparent layered element with diffuse reflection properties includes two outer layers made of dielectric materials having substantially the same refractive index and a central layer intercalated between the two outer layers, formed either from a single layer which is a dielectric layer with a refractive index different from that of the outer layers or a metallic layer, or from a stack of layers which includes at least one dielectric layer with a refractive index different from that of the outer layers or a metallic layer. The upper outer layer is a sol-gel layer including a silica-based organic/inorganic hybrid matrix.

A process for the manufacture of a scattering polymer film can include (a) making available a film made of organic polymer, (b) applying, to one of the faces of the said film, a liquid composition (c) heating and/or irradiating the layer of liquid composition to form a cured scattering layer. A scattering polymer film can be obtained by this process. A substrate for OLED can include such a film adhesively bonded to a transparent substrate.

A glazing, which may be translucent, includes at least one design, which may be transparent. The glazing includes a substrate having two main outer surfaces, at least one of which is a textured surface, made of a dielectric material having a refractive index n1 and at least a part of the textured surface of the substrate is coated with a sol-gel layer made of a dielectric material having a refractive index n2.

Translucent glazing comprising at least one pattern that is preferably transparent

A copolymer includes a first group that is hydrophobic and a second group that is crosslinkable. Moreover, a glass substrate includes a coating of the copolymer, with interposition of a layer of silane including a functional group capable of reacting with the crosslinkable group. The glass substrate may be used as hydrophobic glazing for a transport vehicle, shower cubicle wall or easy-to-clean interior glazing.
