Abstract
An oxime ester compound represented by general formula (I), wherein R1to R8 are as defined in the description, and n is 0 or 1; a photopolymerization initiator containing the compound; a photosensitive composition, alkali-developable photosensitive resin composition, and colored alkali-developable photosensitive resin composition containing the photopolymerization initiator; and a cured product of these compositions are provided. The compound is useful as a high-sensitivity photopolymerization initiator that has good stability and low sublimability and that efficiently absorbs, and is activated by, near-ultraviolet light, e.g., at 365 nm.
