Abstract

See full text

Solvent-based, or water-based, coating compositions are disclosed having primary or secondary amine concentrations of greater than 1.0 mg KOH/g (coating) equivalent. These coatings, when applied over inks or other coatings, reduce the level of materials that cause odor or other contamination problems. These coatings when applied over radiation-cured inks and coatings reduce the level of odor and contamination resulting from uncured monomers and oligomers, and also of photoinitiators and their photodecomposition products.
