Abstract
Abstract An improved process for laser or UV curing of pigmented binder systems comprising ethylenically unsaturated polymer binders containing at least about 0.05 weight parts of opacifying pigment per weight part of binder wherein the pigmented binder system includes from about 0.5% up to about 3% of 2,2''-dithiobis(benzothiazole) synergistic sensitizer in combination with about 0.1 to 2% aromatic amine carbonyl compounds and from about 0.5% to 2% aromatic ketone or aldehyde. The sensitized binder system is a substantially improved system suitable for curing by ultraviolet or laser energy sources.
