    摘要: Photographic silver halide can be stabilized with certain organic sulfonium, organic sulfoxonium, organic ammonium, organic phosphonium, organic boronium, and/or organic siliconium halides of mixtures of these. These can be employed in a photographic element, processing solution or processing web. They are useful in combination with a nonaqueous, low-melting solvent, e.g. succinimide, sulfamide, urea, or acetamide.
