Abstract: A non-leaching adhesive system and its use in a liquid immersion objective for immersion-writing of masters for optical discs are disclosed. The adhesive system comprises at least one monomer, selected from among the group of acrylate and methacrylate monomers, allylic monomers, norbornene monomers, hybrid monomers thereof, containing chemically different polymerizable groups, and multifunctional thiol monomers, provided that said thiol is used in combination with at least one of said non-thiol monomers; and a polymerization initiator. At least one of said monomers, not being a thiol, is provided with at least two functional polymerizable groups to obtain a crosslinked polymer network. The polymerization initiator is preferably an initiator that can be activated both thermally and with UV radiation. The adhesive system may further contain a reactive diluent. Further the use of the present adhesive system in mounting a liquid immersion objective is disclosed.

Abstract: The invention relates to a method of manufacturing a replica, which method comprises the provision of a polymerizable resin composition between a front mold having a pre-shaped surface and a back mold having a pre-shaped surface, carrying out a curing treatment and removing the replica thus manufactured from the molds. The invention further relates to a replica obtained by carrying out a UV light-initiated cationic polymerization.

Abstract: The invention relates to a method of manufacturing a replica, which method comprises the provision of a bondable resin composition between a mold and a substrate or a blank, carrying out a curing treatment and removing the replica thus manufactured from the mold, which replica comprises the substrate and the reproduction of the mold provided thereon. The invention further relates to a replica obtained by carrying out a UV light-initiated cationic polymerization.

Abstract: In a method of manufacturing a replica, a bondable resin composition is provided between a mold and a substrate or a blank, the resin is cured and the replica thus manufactured is removed from the mold. The replica includes the substrate and the reproduction of the mold on the substrate. The curing includes a UV light-initiated cationic polymerization.
