    摘要： The synthesis and the application of new dyes is described, said new dyes being incorporated in non-migratory state in hydrophilic colloid layers of photographic materials wherefrom they can be rapidly removed after being quickly decolorized in alkaline aqueous liquids used in the processing of said materials. The filter dyes have an amide function or a derivative therefrom as a substituent at the mono- or trimethine chain.
