Abstract: A thermoplastic sheet for the manufacture of a transparent motor vehicle or building glazing intended for the display of information, in particular of a laminated glazing, the sheet including a compound exhibiting an absorption band in the ultraviolet region and of which the diffuse reflection spectrum as a function of the energy of the incident radiation is characterized by a V value on the reflection curve, determined by the point of intersection between the tangent (1) at the inflection point of said curve and its asymptote (2) at the higher energies, of between 3.06 and 3.65 eV.

Abstract: A method for producing a film having luminescent particles is described. The method has steps a) mixing a thermoplastic and a luminescent pigment containing a hydroxyalkyl terephthalate of the formulate: R1—COO—P(OH)x-COO—R2 and obtaining a thermoplastic mixture; and b) homogenizing the thermoplastic mixture to 150° C. to 200° C. in an extruder, by way of an extrusion nozzle, and obtaining a thermoplastic film.

Abstract: A conducting substrate includes a dielectric substrate having alkali ions, an electrode coating having a molybdenum-based layer on the substrate, and a stack of several layers between the substrate and the electrode coating. The stack comprises a first layer impermeable to alkali on the substrate, a layer for retention of alkali on the first layer impermeable to alkali and made of another material, and a second layer impermeable to alkali on the layer for retention of alkali and made of a material other than the layer for retention of alkali. The ratio of the thickness of the layer for retention of alkali to the first layer impermeable to alkali is equal to 2 or more.
