The present invention relates to a polymerizable coating composition suitable
for the manufacture of printing plates developable on-press. The coating composition
comprises (i) a polymerizable compound and (ii) a polymeric binder comprising polyethylene
oxide segments, wherein the polymeric binder is selected from the group consisting
of at least one graft copolymer comprising a main chain polymer and polyethylene
oxide side chains, a block copolymer having at least one polyethylene oxide block
and at least one non-polyethylene oxide block, and a combination thereof. The invention
is also directed to an imageable element comprising a substrate and the polymerizable
coating composition.
