Abstract

The present invention describes a light-sensitive copying material comprising a support and a light-sensitive layer which contains from 0.01 to 10 percent by weight of a non-ionic ester which is obtained by reacting a perfluoro-carboxylic acid with a polyalkylene glycol or of an ether which is obtained by reacting a highly fluorinated or a perfluorinated alkanol with a polyalkylene glycol. By the addition of the fluorinated compound, a more uniform coating is achieved, even when one solvent alone is used for the coating solution.
