SENSITIZER FOR CATIONIC PHOTOINITIATORS

摘要

Polycyclic aromatic compounds of formula (I) having at least two conjugated aromatic rings at least one of which has a substituent comprising a cyclic carbonate group can be used as sensitisers for cationic photoinitiators, especially iodonium compounds, and may also function as monomers in cationically initiated radiation curable compositions, especially coating compositions, such as printing inks and varnishes.
