Abstract

L'invention se rapporte aux matériaux photographiques. Elle concerne une pellicule photographique comprenant un support et une émulsion gélatine-halogénure d'argent sur ce support, caractérisée en ce que l'émulsion est appliquée en deux couches et en ce qu'un dénvé de polyoxyéthylène est distribué entre les couches de manière que 60 à 100 % du dérivé de polyoxyéthylène se trouve dans la couche supérieure et 40 à 0 % dudit dérivé se trouve dans la couche inférieure. Application notamment comme pellicules lithographiques.
