A negative-working imagable composition and element includes an initiator composition, an infrared radiation absorbing compound, a polymeric binder, and a stabilizing composition. The imaged element can be developed on-press and exhibits improved shelf-life under high humidity conditions. The stabilizing composition comprising at least one compound represented by Structure (ST-I) and at least one compound represented by Structure (ST-II): wherein m is 1 or 2, n is 1 to 50, R is hydrogen when m is 1, R1 through R3 are independently hydrogen or methyl, and L is an aliphatic, carbocyclic, heterocyclic, heteroatom divalent linking group, or a combination thereof.
