ACID STABLE PHOTOINITIATOR COMPOUNDS, COMPOSITION CONTAINING SAME, USE THEREOF, AND METHODS USING SAME |
| abstract |
The invention relates to compounds of formula I (CF DRAWING IN BOPI) wherein R1 is, for example, a substituted or unsubstituted C1 -C20 alkyl or phenyl (C1 -C6) alkyl radical; R2, R3 and R4 are each independently a substituted or unsubstituted phenyl or biphenylyl radical; the sum of the Hammett sigma constants (SIGMA sigma) of the substituents present on the aromatic radicals R2, R3 and R4 being between +0.36 and +2.58; and G is a radical which is capable of forming positive ions. These compounds are useful as photoinitiators for photopolymerizable compositions which contain acidic groups, optionally in the presence of a co-initiator. Application to photosensitive materials. |
