Multi-layer, negative working imageable elements useful as lithographic
printing plate precursors are disclosed. The elements contain, in order, a support;
an underlayer; and an imageable layer. The imageable layer comprises a negative
working imageable composition; and the underlayer is soluble or dispersible in
a developer. Elements that can be imaged with ultraviolet or visible radiation
and elements that can be imaged with infrared radiation or with heat are disclosed.
