Negative-working, water-developable imageable elements, useful as printing plate precursors, and methods for their use, are disclosed. The elements can be imaged with ultraviolet radiation, with infrared radiation, or with heat. The elements contain an imageable composition that contains a latent Brönsted acid, a water-soluble or water-dispersible binder, and an acid-activated cross-linking agent.
