Abstract:
This invention relates to radiation curable ink compositions comprising one or more mono-functional monomers, optionally one or more oligomers, one or more antioxidants capable to react with peroxy radicals to generate radicals to propagate polymerization, and one or more photoinitiators comprising at least an acylphosphine oxide, wherein the ratio of the antioxidants to acylphpsphine is 1:1 to 1:20 by weight. The ink composition provides tack-free surface cure without requiring nitrogen or other inert gas during curing.
