Characteristics of photographic paper

High hardness and folding resistance. Paper is coated with photosensitive emulsion, and its image can be preserved for a long time after illumination and chemical development.

On the barium base paper made of high-quality photographic base paper, a coating made of barium sulfate and alum glue is evenly coated, then a photographic emulsion made of gelatin and silver halide is coated, and then a protective film is coated on the emulsion coating. By changing the ratio of silver halide to gelatin in photographic emulsion, controlling curing conditions and adding sensitizing pigments, printing papers with different sensitivities were obtained.
