摘　　要：对黑白、彩色相纸所用光谱增感染料在水溶液中的的分散工艺进行改进,成功地去除有机溶剂甲醇的使用,使增感染料稳定的分散在水溶液当中;将该水溶液应用于黑白、彩色感光材料的乳剂中,增感后的乳剂照相性能均达到醇溶液制备水平,在消除有机溶剂对工人健康的危害和对环境的污染的同时,还可降低生产成本。The article describes a method of dispersing the spectral sensitizing in an aqueous system without any organics solvents （such as carbinol or ethanol）. And dispersed homogenously into water in the presence of a surface-active agent using an agitate machine. The thus obtained dispersion is then added to the silver halide emulsion. The method will reduce the cost, at the same time would protect workers＇ health and environment.
