A method for producing a multilayer film, with the steps: a) providing a base body with a carrier ply and a transfer ply, which comprises at least one layer; b) applying an in particular UV-curable adhesive to at least one partial area of the transfer ply of the base body; c) applying a stamping foil which comprises a carrier ply and a transfer ply, with the result that the transfer ply of the stamping foil comes into contact with the transfer ply of the base body coated with adhesive; d) curing the adhesive by UV irradiation; e) removing the carrier ply of the stamping foil.

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.

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.

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 %.

The method comprises a pre-lamination step wherein a layer is placed in contact at least on one side with a lamination plate having a recess and the layer undergoes lamination such that a raised portion is formed on the layer; an assembling step wherein another layer is placed in contact with the layer, and the raised portion of the layer is at least partially placed in an opening of the other layer and a lamination step wherein said layers are laminated together.
