Abstract
A polymerisable radiation-curable composition comprising: (i) monomers, comprising at least (a) a first monomer having a TG (glass-transition point) of the homopolymer of said first monomer ≥120° C. and at least (b) a second monomer having a TG (glass-transition point) of the homopolymer of the second monomer ≤100° C., wherein at least one of the at least one first monomer or of the at least one second monomer has an alicyclic group, and comprising (ii) at least one further component, comprising at least one photo-initiator for the UV and/or Vis spectral region or a photo-initiator system for the UV and/or Vis spectral region. Also disclosed is a blank in the form of a three-dimensional moulded body of a polymerised composition, in particular radiation-cured composition, for producing 3D moulded bodies, dental prosthetic parts, orthopaedic appliances or dental pre-forms in a rapid prototyping, rapid manufacturing, or rapid tooling method.
