Dye image-generating photographic elements |
摘要 |
Photographic elements intended to generate dye images containing at least one colloidal silver layer and at least one hydroquinone antistain agent have been observed to suffer from random fog spotting, which can be reduced by incorporating a catalyst for the decomposition of hydrogen peroxide. The imagewise exposed elements when photographically processed and bleached of silver produce viewable dye images.
