摘要： A process for diazo-type multi-color reproduction by which portions of a sensitive paper corresponding to predetermined portions of an original can be colored selectively to different hues by disposing a layer of thermotransferable coupler between an original and diazophotosensitive paper followed by exposure to light and heating of the assembly. The layer of thermotransferable coupler is not applied to the entire image area of the original and the thermotransferable coupler is faster in coupling rate with the diazonium salt under the development conditions than the basic color coupler of the photosensitive paper or developing solution.
