ABSTRACT:
A photosensitive element comprising, in order a support; a photosensitive layer comprising a photosensitive composition; and a layer comprising a thermally sensitive material; wherein the thermally sensitive material is (a) incompatible with the photosensitive composition, (b) non-tacky and non-blocking at room temperature, and (c) tackifiable at 70.degree. C. to 120.degree. C. and a process for using these elements is described. The photosensitive element may be in sheet or roll form.
