ABSTRACT:
A radiation-sensitive composition includes a radically polymerizable component and a borate initiator composition capable of generating radicals sufficient to initiate polymerization of the radically polymerizable component upon exposure to imaging radiation. This composition also includes a radiation absorbing compound (such as an IR-sensitive dye), a polymeric binder comprising a polymer backbone to which is directly or indirectly linked a pendant group comprising a reactive vinyl group, and a primary additive that is a poly(alkylene glycol) or an ether or ester thereof that has a number average molecular weight of from about 200 and up to 4000 and comprises from about 2 to about 50 weight % based on the total composition solids content. This composition can be used to prepare a negative-working imageable element that can be imaged at relatively low energy and developed without a preheat step.
