ABSTRACT:
Peroxycarboxylic ester photoinitiators derived from aromatic nitrogen containing heterocyclic carboxylic acids are described. The heterocyclic aromatic ring may contain additional nitrogen atoms, be fused with another aromatic ring system, be substituted with an additional peroxycarboxylic ester group and/or be substituted with an electron group having a Hammett sigma value greater than 0.1. The peroxycarboxylic ester photoinitiators have been found to be useful in photopolymerizable compositions and photosensitive elements.
