Abstract (en)

[origin: EP1080883A2] In a laser-engravable recording material for making relief printing plates, which has a dimensionally stable base, a laser-engravable recording layer containing polymeric binder(s) and absorber(s) for the laser radiation and optionally a covering film, the binder is a silicone rubber and the absorber is an inorganic solid containing iron and/or carbon black. Independent claims are also included for: (a) the production of relief printing plates by removing the covering film if necessary and engraving a relief in the material with a laser; (b) relief printing plates comprising a dimensionally stable base and relief with the cited binder and absorber.
