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.

The present disclosure is directed to a curved automotive laminated glazing with an opening, named cutout, in the performance plastic interlayer, such that the edges of said cutout has improved optical properties. Conventionally an opening must be provided onto the performance plastic interlayer such as UV absorbing. IR reflective or other types of solar performance interlayers to aiming to remove any optical disruptions. However, it was discovered that the geometry of the cutout in the performance interlayer plays an important role in the optical distortion measured in the center of the field of view. Therefore, the present invention suggests the use of a cutout geometry having round corners which decrease the optical distortion in the field of view by a factor of three.

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.
