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.

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.
