    • In heat developable photographic system of dry procedure, color images are formed by imagewise exposing and then heating a light-sensitive material comprising a support having provided thereon a light-sensitive layer containing silver halide, a binder, and a compound capable of producing or releasing, upon reduction of light-sensitive silver halide to silver at elevated temperatures, a mobile dye, as a direct or inverse function of the reduction reaction, allowing the produced or released mobile dye to migrate into a dye-fixing material having incorporated therein a hydrophilic thermal solvent and fixing the dye thereto, then separating the light-sensitive material from the dye-fixing material, with a fluorine-containing surfactant being incorporated in at least one of the uppermost layers on the contacting sides of the light-sensitive material and of the dye-fixing material. Adhesion and poor S/N ratio problems accompanied by the use of hydrophilic thermal solvents are improved by incorporating fluorine-containing surfactants into the aforesaid layers.
    • 在干燥程序的可热显影照相系统中,通过成像曝光形成彩色图像,然后加热含有其上设置有含有卤化银,粘合剂和能够产生或释放的化合物的感光层的载体的感光材料 当感光卤化银在升高的温度下还原为银时,作为还原反应的直接或反向功能的可移动染料使得所生产或释放的可移动染料迁移到其中掺入亲水性染料固定材料 热溶剂并固定染料,然后将感光材料与染料固定材料分离,其中含氟表面活性剂被引入到感光材料的接触侧上的最上层中的至少一个和 染料固定材料。 通过在上述层中加入含氟表面活性剂,可以提高伴随使用亲水性热溶剂的粘附性和差的S / N比问题。
