Claim 0:
1. Polymerisable radiation-curable composition for use in generative radiation-curing methods, comprising the following components:
(i) monomers and
(ii) at least one further component, wherein
in the composition are present
(i) 40 to 99.99% by weight (a) a mixture of first monomers having a TG (glass-transition point) of the respective homopolymer of the corresponding first monomer of greater than or equal to 120° C., and comprising at least one triacrylate derived from 1,3,5-tris(hydroxyalkyl) isocyanurate, wherein the hydroxyalkyl residue each independently comprises 1 to 8 C-atoms, and
di-functional acrylates having a bivalent alicyclic group and/or di-functional methacrylates having a bivalent alicyclic group, and
up to 60% by weight (b) at least one second monomer or a mixture of second monomers having a TG (glass-transition point) of the respective homopolymer of the corresponding second monomer of less than or equal to 100° C., comprising at least one mono-functional acrylate having an alicyclic group and/or mono-functional methacrylate having an alicyclic group up to 25% by weight selected from (octahydro-4,7-methano-1H-indenyl) methanol acrylate, (octahydro-4,7-methano-1H-indenyl) methanol methacrylate, (octahydro-4,7-methano-1H-indenyl) ethanol acrylate and (octahydro-4,7-methano-1H-indenyl) ethanol methacrylate, and
(ii) 0.01 to 5% by weight of the 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, and optionally at least one stabiliser for the UV and/or Vis spectral region, and optionally at least one pigment and/or dye as well as further additives,
wherein the total composition of the components adds up to 100% by weight, and
wherein the viscosity of the composition at approx. 20° C. to 23° C. is less than is less than or equal to 3000 m·Pas.
