A photosensitive color proofing article comprising in the following order:
- a) a carrier layer,
- b) a release layer which acts as an oxygen barrier layer,
- c) a photopolymerizable layer comprising a multifunctional acrylate oligomer and a colorant,
- d) a photopolymerizable barrier layer adjacent to layer c), and
- e) a thermal adhesive layer.
A colored photographic element comprising a substrate having sequentially disposed thereon an optional oxygen barrier/release layer, a low tack colored, photopolymerizable, photosensitive layer;
- a photopolymerizable barrier layer;
- and a thermal adhesive layer, said element being developable in an aqueous developer with a pH less than 10.5, and 3% or less solids.
