Crosslinking of relief layers to give laser-engravable flexographic printing forms is effected using electron radiation at above 40kGy total dose, especially stagewise

摘要

Production of flexographic printing forms by complete crosslinking of a relief layer comprising an elastomeric binder and a laser radiation-absorber on a dimensionally-stable support, followed by laser engraving, is such that the crosslinking is effected using electron radiation at a minimum total dose of 40kGy.
