Color-forming para-sulfonamidodiphenylamines and their corresponding sulfonimide dyes are useful in imaging materials. The color-forming sulfonamidodiphenylamines are prepared by condensation reactions. The corresponding sulfonimide dyes are formed by oxidation of the color-forming sulfonamidodiphenylamines by means of a suitable oxidizing agent, such as the oxidized form of a cross-oxidizing silver halide developing agent.
颜色形成的对磺胺基二苯胺和相应的磺酰胺染料在成像材料中很有用。这些颜色形成的磺胺基二苯胺是通过缩合反应制备的。相应的磺酰胺染料是通过适当的氧化剂,如交氧化银卤化物显影剂的氧化形式,氧化颜色形成的磺胺基二苯胺形成的。
