substituted benzoylferrocene as anionic fotoinitiatoren

摘要

The present invention relates to anionic photoinitiator compounds, compositions containing them, and methods of using them having the structure: wherein X and Y are independently selected from the group consisting of a direct single bond and -C(=O)-, wherein at least one of X and Y is -C(=O)-; R1 and R2 are independently selected from the group consisting of H and substituted phenyl, wherein both R1 and R2 are not H; and wherein neither -X-R1 nor -Y-R2 is -C(=O)H. The anionic photoinitiators have improved storage stability, without loss of photosensitivity, even when stored with polymerizable or crosslinkable monomer, oligomer, or crosslinkable polymer species.
