A method is provided for photographic developing using a roll of photographic paper. A photographic image is formed on the paper, and the image-containing portion of the paper cut from the roll of paper. The improvement comprises the end of the roll of paper being initially maintained in place by means of a pressure sensitive adhesive tape comprised of a polyisobutylene-or polybutene-based pressure sensitive adhesive on a backing layer, with the tape being removed prior to the roll being used as a substrate for the photographic image. The combination of a roll of photographic paper whose free end is held in place by the pressure sensitive adhesive is also provided.
