Description
A photographic printing paper made with an arrowroot starch binder that was used in the mid 1850s. A thin layer of arrowroot starch mixed with sodium chloride and citric acid was applied to a photographic paper using the salted paper process. It was dried then treated with silver nitrate to make the image layer photosensitive. Arrowroot starch formed a layer, that once dry, did not swell in water. It was colorless and unreactive to the silver salts. Arrowroot paper produced a bright image with a good density range and high resolution. However, by the end of the 1850s it was replaced in popularity by albumen papers.
