A booklet includes a book block having at least two sheets stitched together. When the sheets are folded along a line parallel with stitching so each sheet defines a leaf on each side of fold line, the sheets form an innermost and outermost sheet. The stitching's obverse side is exposed on the innermost sheet's inner surface and stitching's reverse side is exposed on the outermost sheet's outer surface. A cover member has inner and outer surfaces, the inner surface defining first and second cover pages one on each side of cover fold line. The block is attached to cover member by attaching a block's leaf to first cover page defining a first end page, the block's leaf defining the first end page being selected so the block can be opened in two different configurations to reveal respectively the stitching's obverse and reverse sides without detaching the block from cover member.

A unisometric reflection display having a light transmissivity includes reflectors included in a reflector holding layer of a thin film form. The reflectors incline at a fixed direction and a fixed angle to a plane of the reflector holding layer. Light incident from a first direction is reflected on a front surface of a reflector to be inhibited from transmitting through the reflector holding layer. Light incident from a second direction to a reflector is reflected on a front surface of the reflector and a rear surface of another reflector adjacent the reflector at a front surface side, or reflected this way a plurality of times to transmit through the reflector holding layer.

The present invention relates to a process for the preparation of thin silver nano-particle layers, which are produced directly on a substrate as part of a coating or printing process. The layers show different colours in transmittance and reflectance. The layers do not show the typical conductivity of metallic layers, since the particles are essentially discrete particles which are not sintered. The invention further relates to decorative and security elements. When the layers are applied over a security element, such as a hologram, the obtained products show also different colours in reflection and transmission, an extremely bright optically variable image (OVD image) and high purity and contrast. Depending on the thickness of the layer a more or less intensive metallic aspect appears. 2. A method according to claim 1 , wherein the substrate is a plain substrate.3.

The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission. As will be readily appreciated, the inventive security sheet or document offers greatly improved counterfeit-resistance.

The present invention relates to a process for the preparation of thin silver nanoparticle layers, which are produced directly on a substrate as part of a coating or printing process. The layers show different colours in transmittance and reflectance. The layers do not show the typical conductivity of metallic layers, since the particles are essentially discrete particles which are not sintered. The invention further relates to decorative and security elements. When the layers are applied over a security element, such as a hologram, the obtained products show also different colours in reflection and transmission, an extremely bright optically variable image (OVD image) and high purity and contrast. Depending on the thickness of the layer a more or less intensive metallic aspect appears. 1. A method for forming a silver nanoparticles-containing layer on a substrate , the method comprising:A) optionally forming an optically variable device (OVD) on a discrete portion of the substrate;B) applying a composition on at least part of the substrate, optionally on at least part of the OVD obtained in step A), or both, to obtain a coating; andC) exposing the coating to heat, irradiating the coating with electromagnetic radiation, or both, to form a highly reflective layer comprising silver nanoparticles, b1) a silver metal precursor,', 'b2) an acid,', 'b3) optionally a solvent,', 'b4) an optionally substituted polyhydric phenol, and', 'b5) optionally a polymeric binder., 'wherein the composition comprises2.
