Abstract
A photopolymerization initiator is provided. The photopolymerization initiator contains at least one unsaturated double bond and at least one oxime ester group in the molecule. The photopolymerization initiator comprises a compound represented by Formula 1 or 2: Further provided is a photosensitive resin composition comprising the photopolymerization initiator. The use of the photosensitive resin composition in photolithography reduces the formation of volatile residue during post-development baking.
