Abstract: An information carrier includes information in the form of a hologram. In order to increase protection against copying and/or as a simple recognizable additional security feature of this information carrier, the hologram is the combination of a transmission hologram and a reflection hologram.

Abstract: There is described a photopolymerisable composition comprising (a) 75 to 99% by weight of an ethylenically unsaturated monomer or a monomer mixture of different ethylenically unsaturated monomers, (b) 0.5 to 25% by weight of a triglyceride or a mixture of different triglycerides and (c) 0.1 to 10% by weight of a photoinitiator system which activates the polymerisation of the ethylenically unsaturated monomer(s) upon exposure to actinic radiation, wherein the composition is a homogeneous, clear and, at 20° C., liquid mixture. Furthermore, there are described elements manufactured from such photopolymerisable compositions and methods for the formation of light-resistant holograms therefrom. The photopolymerisable compositions are useful, in particular, as recording material for optical elements having refractive index modulation, in particular, holograms.
