发明名称 Protective top layer and photographic products containing this top layer
摘要 The present invention concerns a photographic material comprising, in addition to the conventional light-sensitive silver halide layers, a protective top layer. According to the invention, the protective layer comprises, in combination, a surface-active fluorinated polyether and a vinyl polymer. This protective top layer enables the appearance of marks during photographic processing to be prevented without modifying the sensitometric results.
