THIOL COMPOUND, PHOTOPOLYMERIZATION INITIATOR COMPOSITION AND PHOTOSENSITIVE COMPOSITION

摘要

A photopolymerization initiator composition containing a thiol compound having a mercapto group-containing group that has at least one substituent on the carbon atoms on carbon atom(s) at the alpha- and/or beta-position with respect to the mercapto group and a photopolymerization initiator; a photosensitive composition containing the composition; and a novel thiol compound for use in these compositions. The photosensitive composition containing the photopolymerizazion initiator composition of the present invention has high sensitivity and excellent storage stability and enables reduction in cost due by increasing productivity.
