ABSTRACT OF THE DISCLOSURE: Process for the production of vesicular recording materials. The photographic characteristics such as speed and contrast of vesicular recording materials are improved by treating the light-sensitive vesicular recording layer with an aqueous medium at 5 to 30°C for at least 45 minutes. The treatment may be effected by spraying with cold water and winding the wet material into a roll. Water marking in the wound roll can be avoided by coating the recording layer prior to water treatment with an anti- marking composition such as a solution of nitrocellulose.
