Article, especially a cooktop or furniture element, containing at least one substrate, such as a plate, made of glass-ceramic, the substrate being coated in at least one zone with paint containing at least: 1) a silicone resin having methyl and phenyl groups, 2) one or more lamellar inorganic fillers with a thickness of less than 2 m and with lateral dimensions, for at least 80% by weight of the fillers, of between 10 m and 65 m, including at least: 2a) mica(s), and 2b) talc and/or one or more carbonates, 3) one or more black pigments. Process for obtaining the article.

A final layer of a multi-layer of thin deposit and lacquer layers of a decorative faceted functional stone formed by 10 to 35% of nano/colloidal silica, optionally nano/colloidal alumina, 30 to 50% of encapsulated aluminium flakes in grain size of 15-80 m, 2 to 10% of Fe3O4 in grain size of 3-50 m, and 10 to 40% of polyisocyanate-hardened mixture of epoxy and polyether resin, and a method for increasing the opacity and hardness of a multi-layer of thin deposit and lacquer layers of a decorative faceted functional stone by applying this final layer.

Disclosed herein is a transparent photothermal composition, which includes nonstoichiometric copper sulfide (Cu.sub.2-xS, 0<x1) nanoparticles dispersed in an acrylic resin, wherein the Cu.sub.2-xS (0<x1) nanoparticles are nanorods independently having an aspect ratio ranged from 2.2 to 3.6 and exhibit at least 95% absorption of a near-infrared (NIR) light ranged from 800 to 1,100 nm. Also disclosed herein are methods of producing the transparent photothermal composition and uses of the transparent photothermal composition in protecting a glass substrate from icing in a cold surrounding.

A display panel according to the present invention includes a display panel and a cover member disposed on the display panel. The cover member includes a glass plate having a first surface and a second surface, at least the first surface being chemically strengthened, and an optical layer that is layered on the second surface of the glass plate and faces the outside. In the glass plate, the depth of the compressive stress layer (dol) in the first surface is larger than that in the second surface.
