PHOTOPOLYMERIZATION INITIATOR COMPOSITION AND PHOTOPOLYMERIZABLE COMPOSITION CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photopolymerizable composition having high resolution and excellent alkali-resistant development and line width stability in an exposed part, and to provide a photopolymerization initiator composition used for the above composition.

SOLUTION: The photopolymerization initiator composition contains a dicarbonyl compound expressed by general formula (1) and a photoradical generating agent (a hexaaryl biimidazole compound and/or an organic borate compound). The photopolymerizable composition contains the above composition.
