    Abstract: Developing dyes are especially easily produced by using preparations containing molar amounts of diazo or coupling components per weight or volume unit or a multiple or a fraction thereof in simple numerical ratios. Since the diazo component is the free finely dispersed amine these preparations are stable and allow the reaction of stoichiometric amounts. Thus, multicolor effects are feasible which hitherto could not be obtained at all or with difficulties only.
