Photoinitiator OXE-01
1-[4-(Phenylthio)phenyl]-1,2-octanedione 2-(O-benzoyloxime)
The oxime ester for low-migration, LED-ready inkjet and packaging inks.
Product Description
OXE-01 is an oxime ester photoinitiator whose long-wavelength absorption reaches toward 400+ nm, making it exceptionally efficient on UV LED arrays. Its photolysis fragments are designed to stay film-bound, keeping migration low — the reason oxime esters displaced older initiators in premium food-packaging inkjet.
It is almost always paired with ITX as photosensitizer, at ratios around 1:1, with combined loadings of 2–4 wt%. The result is the industry-standard LED ink package for compliant packaging.
Key Features
- Long-wavelength absorption — excellent UV LED match
- Low-migration by design for food packaging
- Standard partner for ITX sensitization
- High efficiency at low total loadings
Applications
- UV LED inkjet inks for packaging
- Low-migration food-packaging inks
- Flexo and offset LED systems
- Inkjet primers and varnishes
- Compliant foldig-carton lines
