Abstract
Zinc-complex photoiniators and applications therefore are disclosed. The zinc-complex photoinitiators of the present invention include various pendent groups which serve to protect the compound from hydrolysis. In this manner, the stability of the photoinitiator is increased. The photoinitiators of the present invention can be used in many different processes and applications. For example, the photoinitiators are well suited for use in photocurable inks as used in ink jet printers or on a printing press.
