THIOURETHANE COMPOUND AND PHOTOSENSITIVE RESIN COMPOSITION

摘要

It is an object of the present invention to provide a photopolymerization initiator composition having high sensitivity and excellent storage properties, a photosensitive composition containing the photopolymerization initiator composition, and a thiourethane compound preferable for the photopolymerization initiator composition. The thiourethane compound of the present invention has 2 to 6 units each of which contains a moiety represented by the following formula (i) and a moiety represented by the following formula (ii).
wherein R 1 is a hydrogen atom or a methyl group, and R 2 is - CO-, -COO- or -COOR 3 - (wherein R 3 is an alkylene group of 2 to 6 carbon atoms).
