Abstract:
The present invention relates to a novel photoinitiator system comprising one or more acylphosphine oxide photoinitiators and one or more lightfast red, blue or violet organic pigments. Low yellow color formation results upon curing ethylenically unsaturated compounds with the new photoinitiator system. Particular applications include clear and white coatings, screen inks, gel coats, powder coatings, composites, adhesives and lenses.
