A photosensitive element for use as a photopolymer printing plate comprising a
support, a layer of a photopolymerizable material on the support, and an infrared
ablation layer which is ablatable by infrared radiation and substantially opaque
to actinic radiation on the photopolymerizable material. The infrared ablation
layer comprises at least one infrared absorbing material, a radiation opaque material,
and at least one binder which is substantially incompatible with low molecular
weight materials in the photopolymerizable layer. The infrared ablation layer is
tack-free or substantially tack-free on the photopolymerizable layer. The infrared
ablation layer is ablatable from the surface of the photopolymerizable layer upon
exposure to infrared laser radiation.
