摘要:
The invention relates to a security device comprising a security element composed of: a carrier substrate (1) provided with at least one optically variable effects generating structure (2) situated in defined areas of the said carrier, a first reflective layer (3) visible at least where it coincides with the said optically variable effects generating structures (2) and comprising a reflection enhancing material, at least one second distinctive reflective layer (4) situated only outside the optically variable effects generating structures (2) and comprising a reflective material different from that of the first layer (3). These layers (3,4) can comprise further patterns (7).The invention relates to a security support (9) or document comprising the said security device too.
摘要:
The invention relates to a top part for a shaft, having an access part and a shaft cone which is connected to an access part and, with a connecting element on that side of the shaft cone that lies opposite the access part, can be mounted onto a further shaft element, the shaft cone having a substantially convex basic shape, characterized in that, in the region of the shaft dome, stiffening structures are disposed on the inner surface of this shaft dome, which extend substantially radially or parallelly, angularly or concentrically from one or more imaginary points or lines within or outside the dome downwards over the curved shape of the shaft cone.
摘要:
The invention relates to a system, security elements and security features with colour effects, which can be produced by vapour deposition in a PVD or CVD process, processes for their production and their use.
摘要:
A tamper-proof security element includes at least one polymer spacer layer and two metal cluster layers. One or more of the layers, in addition to their function, fulfills a security feature in their color-shift set-up.
摘要:
The invention concerns a plastic foil for packages designed for packaging cereals and cereal-based preparations. The invention is characterized in that said plastic foil consists of several layers among which one heat sealed layer, one HDPE layer and optionally one polypropylene layer, the opposite surface of the heat sealed layer being provided with a metal-coated barrier layer.
摘要:
A partially vapor-deposited metallized film is disclosed including a metallized film that is vapor-deposited across the entire surface, and a metallized film that has been coated a number of times and also a method for producing a partially vapor-deposited metallized film, a metallized film that is vapor-deposited across the entire surface, and a metallized film that has been coated a number of times, wherein either a structure is printed onto a substrate or onto a supporting film with a soluble ink (washable ink) or the base materials are directly cleaned in a vacuum by means of plasma processing and are simultaneously initiated with target atoms, and wherein a metal or the like is vapor-deposited thereon followed by a production of the structured layer, for multiple uses, for example, in securities, as a radio frequency antenna for transponders and the like.

摘要:
The invention relates to a method for producing tamper-proof identification elements, and to tamper-proof identification elements produced according to said method and consisting respectively of at least one layer (2) reflecting electromagnetic waves (3), a spacer layer, and a layer consisting of metallic clusters (4). According to said method, a partial or all-over layer reflecting electromagnetic waves is applied to a carrier substrate (1), followed by at least one partial and/or all-over polymer layer having a defined thickness (3), and a layer consisting of metallic clusters which is produced by means of a method using vacuum technology or from systems based on solvents is then applied to said spacer layer(s).
摘要:
The invention relates to films for packaging purposes, particularly even blister films, which have a partially applied security feature. The application of the security features ensues by detaching the security feature from a supporting substrate, which is provided with a UV-curable separating paint that is capable of being deep-drawn.
