Document Type and Number:
WIPO Patent Application WO/2010/140547
Kind Code:
A1
Abstract:
Disclosed is a photopolymerization initiator which comprises an iodonium compound of general formula (1) and in which the number of reverse mutation colonies determined through a test for examining the ability to induce reverse mutation (Ames test) using a base pair substitution variant and a frameshift variant is up to twice the number of reverse mutation colonies for a negative control. (In formula (1), A- represents a perchlorate ion, tetrafluoroborate ion, hexafluorophosphate ion, hexafluoroantimony ion, alkylsulfonate ion, or arylsulfonate ion.)
