Known Application

1-[9-Ethyl-6-(2-methylbenzoyl)-9H-carbazol-3-yl]ethanone 1-(O-acetyloxime) CAS 478556-66-0 is a very efficient solid photoinitiator, especially suitable for For applications requiring extremely high photosensitivity. It has higher photosensitivity but slightly less resistance to yellowing. It has an absorption band in the range of 300-400nm, the peak wavelength is 340nm, the absorption edge reaches 400nm, and is sensitive to light at or below the i-line (365nm). And 1-[9-Ethyl-6-(2-methylbenzoyl)-9H-carbazol-3-yl]ethanone 1-(O-acetyloxime) has excellent curing performance in high-pigment photoresist formulations, often used in colored photoresists (RGB glue) and black photoresists (BM glue):
In addition, it can also be used in photosensitive polyimide formulations , LCD isolation materials, microlens materials, outer coatings, dielectric layers and insulating layers.
It is highly soluble in solvents such as propylene glycol monomethyl ether acetate (PGMEA) and cyclohexanone, which are commonly used in color filter photoresists.
