摘要： 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: wherein R1 and R2 are each independently —CH3, —C2H5, —C3H7 or —C6H5; wherein R3, R4 and R5 are each independently —CH3, —C2H5, —C3H7 or —C6H5. 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.
