Abstract
A direct-to-plate flexographic printing plate precursor is disclosed including in the order given, a flexible support, a photopolymerizable layer containing an elastomeric binder, an image recording layer including a thermoplastic binder and optionally a cover layer characterized in that the image recording layer and the photopolymerizable layer can be liquefied so that they can be penetrated to a depth of at least 5% at a temperature of 110° C. by a ballpoint probe having a diameter of 3 mm, which is subjected to a force of 0.1 N. Furthermore, a method is provided for making a direct-to-plate if lexographic printing plate precursor.
