    摘要： Photographic elements are disclosed which comprise a support and at least one layer thereon containing a ballasted resorcinol. In one embodiment, the ballasted resorcinols are utilized as scavengers for development reaction by-products or contaminants. The ballasted resorcinols are especially useful for scavenging oxidized color developers.
