Abstract
The invention relates to photoactive oligomeric aminoketones for compositions and inks curable with ultraviolet (UV) light. The oligomeric ketones are particularly useful for printing or coating materials wherein a low migration of photoinitiators, and reduced transfer of ink from the printed to another surface are desired, such as, for example, food packaging.
