Abstract: The present invention provides oxime ester compounds represented by general formula (I), a photopolymerization initiator using said compound, and a photosensitive composition, alkali-developable photosensitive resin composition, and colored alkali-developable photosensitive resin composition containing same, and cured products thereof. The compounds of the present invention have excellent stability and low sublimability, and are useful as highly sensitive photopolymerization initiators that are activated by efficiently absorbing near ultraviolet light of 365 nm, etc. (I) (See the Specification for the definitions of R1-R8 in the formula. n represents 0 or 1.)
