1. A method of making a relief image, the method comprising:
imaging an imageable material to form an imaged mask material, exposing a relief-forming material with curing radiation through the imaged mask material while they are in complete optical contact, to form an imaged relief-forming material with exposed regions and non-exposed regions, and developing the imaged relief-forming material to form a relief image by removing its non-exposed regions using a developer comprising more than 50% (by volume) of one or more non-chlorinated organic solvents,
wherein the imageable material consists essentially of, in order:(a) a transparent polymeric carrier sheet,(b) a barrier layer disposed directly on the transparent polymeric carrier sheet, the barrier layer comprising a first infrared radiation absorbing compound and at least 50 weight % and up to and including 99 weight %, based on total dry barrier layer weight, of one or more heat-combustible polymer binders that is nitrocellulose, a poly(alkyl cyanoacrylate), or a combination thereof,wherein either or both of the transparent polymeric carrier sheet and barrier layer further comprise a first ultraviolet radiation absorbing compound, and(c) a non-silver halide thermally sensitive imageable layer disposed directly on the barrier layer, the non-silver halide thermally sensitive imageable layer comprising a second infrared radiation absorbing compound and a second ultraviolet radiation absorbing compound, both dispersed within a polymeric binder,wherein the first ultraviolet radiation absorbing compound and the second ultraviolet absorbing compound are same or different UV-absorbing dyes, and the total amount of the first ultraviolet radiation absorbing compound in either or both of the transparent polymeric carrier sheet and the barrier layer, is less than the amount of the second ultraviolet radiation absorbing compound. |
