Claim 6:
7. Composition according to claim 1, wherein there are in the composition (i) monomers comprising
70 to 99.99% by weight (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., wherein the mixture of first monomers comprises at least one triacrylate derived from 1,3,5-tris(hydroxyalkyl)isocyanurate, wherein the hydroxyalkyl residue each independently comprises 1 to 8 C-atoms, at least one di-functional methacrylate having a bivalent alicyclic group, and optionally at least one di-functional urethane (meth)acrylate selected from di-functional urethane (meth)acrylates having a bivalent alkylene group, and
up to 30% by weight at least (b) 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., wherein the second monomer or the mixture of second monomer comprises at least one monomer or a mixture of second monomers having a TG of the respective homopolymer of greater than or equal to 30° 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
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 usual additives, wherein the total compositions amounts to 100% by weight.
