A multi-layer identification patch includes a reflective background layer comprising a front side to face away from a garment when the multi-layer identification patch is affixed to the garment, and a mask layer secured over the front side of the reflective background layer. The mask layer comprises (a) an opaque layer of flexible polyvinyl chloride (PVC) and (b) a void in the opaque layer of flexible PVC. The void has a shape that forms an identification symbol. The opaque layer of flexible PVC is secured over a first portion of the reflective background layer, thereby fixing the void that forms the identification symbol over a second portion of the reflective background layer, and thereby enabling the second portion of the reflective background layer to reflect light through the void in the shape of the identification symbol. Other embodiments are described and claimed.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.

A detectable dust-proof paper is provided. The detectable dust-proof paper includes a detected layer, a first plastic layers, and a first ink-receptive layer. The detected layer has two opposite surfaces. The detected layer includes at least one metal which is selected from the group consisting of: aluminum, copper, nickel, iron, and a mixture or an alloy thereof. The first plastic layer is disposed on one of the two surfaces of the detected layer. A material of the first plastic layer is selected from the group consisting of: a polyolefin, a polyester, a polyamide, and any combination thereof. The first ink-receptive layer is disposed on the first plastic layer. The first ink-receptive layer contains an inorganic ink-absorption material ranging between a value larger than 0 wt % and 75 wt %.

In a method of laminating a transfer layer to a substrate, a transfer layer is provided on a carrier layer. Portions of the transfer layer are selectively removed from the carrier layer using an adhesive panel by heating portions of the adhesive panel corresponding to the portions of the transfer layer, and transferring the portions of the transfer layer from the carrier layer to the adhesive panel. A transfer section of the transfer layer is then transferred from the carrier layer to a surface of the substrate by fracturing the transfer layer along an edge of the transfer section.

The disclosure provides a method for forming an information carrying card or a core layer of an information carrying card using a radiation curing, and an apparatus configured to provide such a radiation curing. The method includes providing a carrier layer that defines at least one cavity, providing an inlay layer supporting at least one electronic component, and positioning at least a portion of the inlay layer in the at least one cavity. The method further comprises dispensing a radiation crosslinkable polymer composition over the inlay layer, and irradiating the radiation crosslinkable polymer composition.

The present disclosure pertains to a tamper indicating security device, which indicates unauthorized duplication of and/or access to a variety of secure documents, technologies, products, and/or protected volumes.

Disclosed herein is an intrusion resistant thermal laminating film having a first multilayer structure of a polyester polymer layer and an ethylene methyl acrylate copolymer layer adhered thereto. The first multilayer structure is exposed to UV radiation for an effective period. A first adhesive layer is on the first multilayer structure and is an ethylene vinyl acetate copolymer or an ethylene ethyl acrylate copolymer. The film also has a printed layer of a polyolefin or a polyvinyl chloride attached to the adhesive layer. The film has high clarity and is free of a primer. The printed layer cannot be separated from the first multilayer structure without destroying the film. The film exhibits no signs of orange peel.
