Accelerators that can be useful for an energy polymerizable composition
comprising a cationically curable material; energy polymerizable compositions comprising
at least one cationically curable material and an initiation system therefor, the
initiation system comprising at least one organometallic complex salt and at least
one accelerator; and a method for curing the compositions. The cured compositions
can provide useful articles. The invention also provides compositions of matter
comprising an organometallic complex salt and at least one compound selected from
the Class 1 through Class 4 compounds disclosed herein.
