A photosensitive element which comprises a support bearing a layer of negative-working tonable photoimaging composition comprising at least one organic polymeric binder (a), a photosensitizer (b) which generates an acid upon absorption of actinic radiation, and at least one compound taken from the group of <IMAGE> (c) <IMAGE> (d) as defined, binder (a) being plasticized by the decomposition product of either compound (c) or (d) or the combination thereof. The photosensitive element is useful in making color proofs.
