摘要

resin sensitivity of the photopolymerization initiator for the photopolymerizable composition used for forming the black matrix and so on to, Common contain the oxime ester compound represented by the formula (I). R ¹ is a hydrogen atom, an alkyl group, an alkenyl group, a heteroaryl group or a heteroarylalkyl group. R ¹ are combined to form a ring with X and Y. R ² is an alkanoyl group, an alkenyl noilgi, cycloalkenyl, alkanoyl, weather aryl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heteroaryl group, a heteroaryl group or an alkylaminocarbonyl group. X is two or more condensed rings are formed, a divalent aromatic hydrocarbon group and / or an aromatic heterocyclic group. Y is a monovalent groups of the phenyl group or the aromatic heterocyclic ring derived stage, at least one ring is a condensed ring group consisting of the condensation.
