Many archive documents were inundated during the catastrophic flood in 2002 in the Bohemia, dominantly in many Prague central institutions and archives. The documents were frozen in huge packets just after the water receded and at present they are saved in freezing storages at the temperature under -30 ?C. The frozen materials usually contain various kinds of documents, dominantly on paper with written of printed information. A significant part of the material is photographic materials, both negatives and positives. The vacuum sublimation called lyophilisation is the most effective process. This work presents the first results obtained during the study of positive photographic materials lyophilisation.
