Known Application
1-[4-(Phenylthio)phenyl]-1,2-octanedione 2-(O-benzoyloxime) CAS 253585-83-0 is a highly efficient photoinitiator, especially suitable for applications requiring high photosensitivity and low yellowing. It has an absorption band in the range of 300-400nm, the peak wavelength is 325nm, the absorption edge reaches 400nm, and it is sensitive to light at or below the i-line (365nm). Highly soluble in solvents such as propylene glycol monomethyl ether acetate (PGMEA) and cyclohexanone, which are commonly used in color filter photoresists.
1-[4-(Phenylthio)phenyl]-1,2-octanedione 2-(O-benzoyloxime) has excellent curing properties in highly pigmented photoresist formulations and is commonly used in color filter photoresists and black matrix photoresists. In resist (BM glue): In addition, it can be used in photosensitive polyimide formulations, LCD isolation materials, microlens materials, outer coatings, dielectric layers and insulating layers.
