To provide a new thiol compound, a photopolymerization initiator composition containing the thiol compound and having high sensitivity and excellent storage stability, and a photosensitive composition containing the photopolymerization initiator composition.
The photopolymerization initiator composition contains a thiol compound having a mercapto-containing group having a substituent on the carbon atom of the α-position and/or the β-position based on the mercapto group and a photopolymerization initiator. There is also provided a photosensitive composition containing the initiator composition and a new thiol compound to be used in these compositions. The photosensitive composition containing the photopolymerization initiator composition has high sensitivity and excellent storage stability and enables the reduction of cost by the improvement of the productivity.
