The light-induced crosslinking polymerisation of the UV-curable acrylate in
ks based on2,2-bis(hydroxymethylpropan-1-ol triacrylate) was investigated b
y IR spectroscopy. During curing, a decrease in tbe absorption band at 810
cm(-1) was monitored, indicating the disappearance of double bonds in the o
riginal ink. The optimum quality of the photocured layer was obtained after
a 10-min exposure under given experimental conditions.
