There is described process for producing security papers, in particular banknotes, comprising the step of sealing the surface of the security papers by applying a protective pattern on the surface of the security paper, which sealing comprising printing the security papers by intaglio printing using an intaglio printing plate with engraved areas such that at least 80% of the whole surface of each security paper is covered with embossed intaglio patterns produced by engraved areas of the intaglio printing plate which are inked or with a combination of embossed intaglio patterns and flat intaglio patterns, which flat intaglio patterns are produced by unengraved areas of the intaglio printing plate which are inked after wiping of the intaglio printing plate, at least a part of the embossed intaglio patterns and / or flat intaglio patterns being printed with a transparent or semi-transparent intaglio ink. The transparent or semi-transparent intaglio ink is applied in engraved areas and / or unengraved areas of the intaglio printing plate so as to seal substantially the whole surface of the security papers with a protective pattern composed of intaglio patterns. Also described are intaglio printing presses for implementing the said process and the resulting security papers.

A light diffusing member which has an excellent surface protection effect while keeping an antireflection effect, and is used in a transmitting screen. The transmitting screen-use light diffusing member comprises a hard-coat layer provided on the surface of a base material consisting of at least one layer, wherein the base material includes fine particles, and the surface glossiness of the hard-coat layer is 60-80 under measuring conditions of an incident angle of 60 DEG / reflection angle of 60 DEG when the surface glossiness of a gloss standard sheet is 100.

The invention provides a folding frame, a displayer, a keyboard and an electric appliance. The folding frame comprises hinges and limiting structures. The hinges are connected through rotary connecting structures, and can be unfolded or folded. Each hinge of the folding frame comprises a front side face and a rear side face. The limiting structures guarantee that the front side faces of the hingesare located on the same plane when the folding frame is in an unfolded state. The rotary connecting structures comprise first rotary connecting structures and / or second rotary connecting structures.One connected hinge rotates to the front side face close to one side, and another connected hinge rotates to the rear side face close to one side. In a folded state, a circle with the minimum bendingradius of a flexible membrane can be contained between the side face of one connected hinge and the rotating axis, the side face of another connected hinge adapts to the flexible membrane, or a gap isformed between the side face of the one connected hinge and the flexible membrane. The displayer comprises the folding frame and a flexible displayer attached to the folding frame. The electric appliance comprises a circuit module, a power module and the displayer. The power module is electrically connected with the circuit module and the displayer, and the displayer is electrically connected with the circuit module. The displayer and the electric appliance can be folded and are convenient to store and carry.

A copolymer in which from 45 to 60% by mass of all monomer units are unsaturated monomers having a specific carbosiloxane dendrimer structure is disclosed, along with a composition, a cosmetic raw material, and a cosmetic containing the copolymer. The copolymer has excellent physical properties, including compatibility with other cosmetic raw materials, e.g. hardly soluble ultraviolet absorbers, and is capable of improving the compounding stability of cosmetics. The copolymer imparts cosmetics with good water resistance, sebum resistance, luster, tactile sensation, and adhesiveness to the hair or skin.

Provided is a method for producing a glass unit. The method comprises a step (A) of obtaining a glass plate; a step (B) of applying a protective sheet to one face of the glass plate; an optional step (C) of subjecting the glass plate to at least one process selected from the group consisting of transportation, storage, processing, washing and handling; a step (D) of removing the protective sheet from the glass plate; and a step (E) of assembling a glass unit using the glass plate. The protective sheet comprises a substrate layer, and a PSA layer provided to at least one face of the substrate layer. The PSA layer has a surface hardness of 0.3 MPa or greater.

The invention provides a laminated polyethylene resin foaming sheet, which could prevent foaming sheets from mutual attaching or attacking on packaged goods such as a glass substrate, has excellent packaged goods packing operation, avoids peeling static electricity and prevents dusts from attaching on packaged goods. The laminated polyethylene resin foaming sheet is laminated with a polyethylene resin layer including a polymeric antistatic agent on at least one surface and is a laminated sheet having a thickness of 0.2-2.0mm and an apparent density of 0.02-0.1g / cm3. The laminated polyethylene resin foaming sheet is characterized in that the laminated sheet at least meets optionally a requirement in specific conditions (i), (ii) and (iii).
