Claim 8:
9. A process of producing the photopolymerizable composition according to claim 1, the process comprising blending:
a) from 40 wt. % to 70 wt. % of at least one urethane component;
b) from 25 wt. % to 70 wt % of at least one monofunctional reactive diluent;
c) from 0.1 wt. % to 5 wt. % of at least one initiator; and
d) from 2 wt. % to 10 wt % of at least one amine-functional (meth)acrylate monomer,
e) optionally, at least one multiple-functional reactive diluent,
f) optionally, from 0.001 wt. % to 1 wt. % of an inhibitor,, wherein the wt. % in all instances is based on total weight of the photopolymerizable composition, and wherein the amine-functional (meth)acrylate monomer is selected from the group consisting of diethylaminoethyl methacrylate, diethylaminoethyl acrylate, dimethylaminoethyl methacrylate, 2-(diisopropylamino)ethyl methacrylate, and N-[3-(dimethylamino)propyl]methacrylamide.
