Problems solved by technology

[0008] However, when a known oxime ester compound is used as a photoinitiator, it causes a pattern shape defect in the printing process due to light-induced degradation at the time of exposure to attach to a mask, and leads to a decrease in yield
[0009] In addition, the decomposition temperature is lower than 240°C, and there is a problem that the adhesion and alkali resistance of the photopolymerizable composition are lowered due to the decomposition of the photoinitiator in the thermal curing step after the development process
