    Abstract: The present invention provides an article having a water- and oil-repellent surface layer, as well as excellent water- and oil-repellent properties, abrasion resistance (resistance to abrasion by eraser), and slipperiness, said article being constituted from: a glass substrate; an underlayer formed upon the outer surface of the glass substrate and having a silicon oxide as the main component thereof; and a water- and oil-repellent surface layer formed upon the outer surface of the silicon oxide underlayer. The film density of the silicon oxide underlayer is 1.8-2.2 g/cm3. The water- and oil-repellent surface layer has, as the main component thereof: a fluoropolyether group-containing polymer having a hydrolyzable silyl group with a specific structure; and/or a cured product of a partially hydrolyzed condensate thereof.

    Abstract: A mirror furniture door have a layered structure. They comprise two mirrors (1,2) connected together by bonding their back surfaces dusted with a layer of metal and covered by protective varnish (3). The mirrors (1,2) are connected by means of a connecting EVA (ethylene-vinyl acetate) film layer (4). The door on both sides comprises the mirrors (1,2), wherein both said mirrors are bonded together by means of the EVA film layer (4) separating them. Each of the mirrors (1,2) comprises opaque or transparent zones (5), without the protective varnish (3) and dusted metal layer. The opaque or transparent zones (5) in both mirrors (1,2) put together overlap one another, so that in the mirrors (1,2) bonded together light can pass through the opaque or transparent zones (5). At least one opaque or transparent zone (5) of at least one mirror (1,2) comprises an additional EVA film (6) sheet.
    A method of manufacturing the mirror furniture door involves cutting the two mirrors (1,2) to size, and then sandblasting the zones of the mirrors (1,2) to be opaque or transparent in a sandblasting chamber to remove the protective varnish (3) layers from these places. Between the back surfaces of the mirrors (1,2), the EVA film layer (4) is arranged, and the furniture door leaf arranged in this manner is subjected to lamination to liquefy the EVA film layer (4) and bond the two mirrors (1,2) together. Before the start of lamination, the door assembly is placed under vacuum. In the first stage in the lamination zone the temperature is increased to 60°C-80°C and this temperature is maintained for a period of about 20-40 minutes. Then, in the second lamination stage, the temperature in this lamination zone is increased to 110°C-135°C and this temperature is maintained for 20-40 minutes. When the annealing is finished, the temperature in the annealing zone is decreased to the ambient temperature.
