Beschreibung
Zusammenfassung:	The invention relates to digitally exposable flexographic printing elements for producing flexographic printing plates, said elements comprising an organically soluble relief-forming layer, a water-soluble barrier layer for oxygen, in addition to a water-soluble laser-ablatable mask layer. The invention also relates to the production of flexographic printing plates using flexographic printing elements of this type, said method comprising a two-stage washout method using aqueous and organic washout agents. L'invention concerne des éléments flexographiques pour imageage direct destinés à la fabrication de clichés, lesquels éléments comprennent une couche soluble en milieu organique destinée à former le relief, une couche hydrosoluble faisant barrière à l'oxygène ainsi qu'une couche hydrosoluble formant un masque d'ablation laser. L'invention concerne également un procédé de fabrication de clichés mettant en oeuvre lesdits éléments flexographiques, lequel procédé comprend un procédé de lavage en deux étapes mettant en oeuvre des agents de lavage aqueux et organiques.
