Patent ID: 8198012

Claim:
A method of making a relief image, the method comprising: A) forming a mask image by forming exposed and non-exposed regions in an imaged film, which film prior to imaging, comprises: a transparent carrier sheet having thereon at least one non-silver halide thermally sensitive imageable layer and a UV-absorbing colorant disposed in the imageable layer, an infrared radiation absorbing compound dispersed in a polymeric binder, and a transparent layer disposed between the carrier sheet and the imageable layer, which transparent layer has a thickness of from about 0.4 μm to about 10 μm and a refractive index that is at least 0.08 lower than the refractive index of the carrier sheet or lower than the refractive index of any optional immediately adjacent layer between the carrier sheet and the transparent layer, B) transferring the mask image in the imaged film to a radiation-sensitive element while there is complete optical contact between the mask image and the radiation-sensitive element, C) exposing the radiation-sensitive element to curing radiation through the mask image while in complete optical contact with the radiation-sensitive element, to form an imaged element, wherein the mask image is opaque to the curing radiation, and D) developing the imaged element to form a relief image having an average shoulder angle of at least 50°.
