A New Thermosensitive Film.

In continuation of our works concerning digital processes' materials we have developed a |dry+ film intended for transparencies' making at the laser systems equipped with IR-laser sources having wavelengths from 0.85(m to 10.6(m. The film consists of a polyester base on which a polymeric layer having a low thermal stability is coated. The image recording on such a material is a result of laser ablation of a thermosensitive layer. The resulting transparency needs no additional treatment. The high optical density of the initial polymeric layer, the low minimal density and the high edge sharpness allow such transparencies using for photopolymeric platemaking in letterpress as well as for conventional offset platemaking.
