| description | An improved process for the diazo-type multicolor reproduction which can give multicolored copies excellent in the hue separation and can increase the number of copies obtained from an original treated with a color-forming agent is disclosed. This improved multicolor reproduction process is characterized by the use of a color-forming composition comprising a thermo-volatile or sublimable coupler and at least one hue separation-improving agent selected from polyalkylene oxides and polyalkylene oxide derivatives which are solid under normal conditions and fatty acid derivatives having a melting point of at least 100 DEG C. |
