Can you please send that reference? I would like to see it. Here are
some UV curable epoxy papers (and related- they are not all epoxies)
that I have found-

PMMA might be a candidate, but I have not looked at the absorption
spectra. Someone once told me that UV as well as blue wavelengths
might be able to do lithography/masked curing of structures.
