    Abstract: A process for the diazo-type multicolor reproduction which comprises (A) exposing to light a diazo-type photosensitive material having a photosensitive layer containing at least one diazonium salt (c) and a coupler (b) having a substantially lower rate of coupling with the diazonium salt (c) than that of resorcin, said coupler being present in the photosensitive material in an amount of not greater than 1 mole per mole of said diazonium salt (c), and (B) heating a layer of at least one thermovolatile or thermosublimative coupler (a) disposed in a face-to-face contact with said photosensitive material at a predetermined portion, said steps being carried out coincidentally or in the order of (A) to (B) or (B) to (A), and then developing the exposed photosensitivematerial. photosensitive material.

    Abstract: A process for diazo-type multicolor reproduction according to which it is possible to obtain multi-colored copies in which portions corresponding to predetermined portions of an original area colored selectively in different hues without substantial mingling of colors, by conducting the heat transfer at relatively low temperatures (for instance, at 60* - 80*C.), and a color former to be used in such process, which comprises a thermosublimative coupler and a thermosublimative, organic, solid transfer promotor having no coupling property in itself.
