White to Light yellow powder to crystal | [Application]
1-[4-(Phenylthio)phenyl]-1,2-octanedione 2-(O-benzoyloxime) may be used after adequate testing in UV curable photoresist formulations either alone or in combination with other photoinitiators or sensitizers. It has also been found helpful in photosensitive polyimide formulations, spacer materials for LCD, microlens materials, overcoat layers, and dielectric or insulating layers.
| [Definition]
1-[4-(phenylthio)phenyl]-1,2-octanedione 2-(O- benzoyloxime) (OXE01; HRcure-OXE01) is a photoinitiator. The promotion of dark polymerization depends on the photoinitiator. Promotion of dark polymerization was observed in the case of OXE01 as it is less susceptible to the radical quenching of oxygen[1].
