22 Claims

1. Polymerisable radiation-curable composition comprising

(i) monomers and

(ii) at least one further component,

wherein

(i) the monomers comprise at least

(a) one first monomer having a TG (glass-transition point) of the homopolymer of said first monomer of greater than or equal to 120° C. comprising

di-functional acrylates having a bivalent alicyclic group and/or di-functional methacrylates having a bivalent alicyclic group and

at least one di-functional urethane (meth)acrylate selected from di-functional urethane (meth)acrylates having a bivalent alkylene group,

and at least

(b) one second monomer having a TG (glass-transition point) of the homopolymer of the 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, and

(ii) the at least one further component comprises 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, wherein the viscosity of the composition at approx. 20° C. to 23° C. is less than or equal to 3000 m·Pas.
