Abstract

Cette invention présente une couche de recouvrement se prêtant bien à une application sur une plaque lithographique, un composé cristallin, soluble ou dispersable dans de l'eau ou de l'eau de mouillage, étant incorporé à cette couche. Il est possible de l'utiliser comme barrière à l'oxygène et/ou pour obtenir une surface qui ne poisse pas sur la plaque d'impression. Du fait de l'incorporation du composé cristallin, les possibilités d'enlèvement en machine de la couche de recouvrement sont améliorées.
