Abstract: The invention relates to a method of producing decorative paper which is coated with at least one ink-fixing layer, which is printable and which can be impregnated with a thermosetting resin, in order to produce a high- or low-pressure decorative laminate. The inventive method comprises the following steps consisting in: (a) producing a base sheet of decorative paper using paper-making means; and (b) coating at least one of the faces of the base paper sheet with said at least one ink-fixing layer, by means of curtain coating. The invention also relates to high- or low-pressure decorative laminates comprising such decorative paper.

Abstract: A catadioptric projection lens for projecting a pattern located in an object plane onto an image plane without an intermediate image includes the following components between the object plane and the image plane in the given order: a first lens part for creating a beam that is directed at a physical beam splitter, a physical beam splitter with a beam splitter surface, a mirror group with a concave mirror, and a second lens part with positive focal power to create an image of the pattern on the image plane. The mirror group preferably has no free-standing lens, and the focal power of the mirror group is largely determined by the magnification of the concave mirror. The focal power of the mirror group is large enough to convert the incident divergent beam into a convergent beam. The system aperture is located on the image side behind of the concave mirror, preferably at the exit of the beam splitter.

Abstract: The invention relates to a portable reader (1). The reader is characterized in that it comprises a part (2) for electric connection to the port of a computer, whereby said part (2) exhibits four conduction lines (8, 9, 10, 11) in addition to a part (4) for the insertion of a module (5) which is removable and which can store confidential information, comprising the body (27) of a plastic module which is substantially parallelepipedal and rectangular whereby the dimensions thereof are 25 mm long, 15 mm wide and 0.76 mm thick, further comprising an integrated circuit chip provided with contact pads which are electrically connected to contact pads (28) which are flush with one of the surfaces of said module, whereby the insertion part comprises a connector which has pins which are electrically connected to the electric connection lines of the reader and, when the module (5) is inserted into said reader (1), to the contact pads (28) of said module (5).

Abstract: The invention relates to a decorative paper sheet, made impregnable by a thermosetting resin, characterized in that it comprises one or more polymers making the 60-second Cobb water absorption value of the sheet, determined according to the ISO 535 standard, at most 40% less than the grammage of the said sheet. It also relates to a decorative sheet impregnated with a thermosetting resin and the laminated decorative panels or moulded section which include it. The invention also relates to a process for manufacturing the sheets as well as to the decorative sheets impregnated with a thermosetting resin.

Abstract: The invention relates to a paper sheet containing grit particles giving it, in use, a high abrasion resistance. It is characterized in that it contains grit particles coated in a non-abrasive material, in particular in a polymer. According to the invention, the particles are chosen from alumina, silica, boron nitride, silicon carbide, titanium carbide, tungsten carbide, zirconium oxide, cerium oxide, glass and ceramic particles, or mixtures thereof. The invention also relates to the laminates containing it, as well as to the processes for manufacturing the sheets and the laminates.

Abstract: The invention relates to an impregnated sheet. It is impregnated with a composition containing, as a mixture, a crosslinkable polymer having a glass transition temperature of between -10.degree. and 35.degree. C., used in the form of a stable aqueous dispersion, other than a styrene/ethyl acrylate/butyl acrylate copolymer, and a water-soluble binder. According to the invention, the water-soluble binder is chosen from poly(vinyl alcohol), gelatin, starches, cellulose derivatives, alginates and mixtures thereof. Application to laminated decorative coverings.
