Beschreibung
Zusammenfassung:	The invention relates to a shaped body and a process for its production by means of a radiation-induced printing process, characterized in that the shaped body is produced from a liquid or viscous material which contains a starting component with cycloolefinic groups, a thiol with at least two thiol groups per molecule and an initiator and/or catalyst for the light-induced thiol-ene addition reaction between the thiol groups and a double bond of the cycloolefinic groups, and the solidification takes place by directing light from a radiation source onto a region of a surface of a substrate, a layer of the liquid or viscous material located there being subjected to organic polymerisation by the action of radiation and thereby solidified, whereupon further layers of the liquid or viscous material, which are each located on the layer of the most recently solidified material, are successively solidified with the aid of this radiation source.
