Abstract
High-contrast room-light-handleable contact-exposed ultraviolet-sensitive black-and-white silver halide photographic elements useful in the field of graphic arts are provided with an electrically-conductive layer which serves to provide antistatic protection. The electrically-conductive layer is comprised of electrically-conductive metal-containing particles, such as particles of antimony-doped tin oxide, a film-forming polymer, such as gelatin, and an ultraviolet-absorber, such as a solid particle filter dye, in an amount sufficient to provide halation protection.
