Abstract
The invention relates to a process for encapsulating solutions of reactants of color reaction systems by means of conventional encapsulation processes, the reactant initially being dissolved in a solvent with a good dissolving power and immediately prior to emulsification or encapsulation, a non-solvent, which only dissolves the reactant to an insignificant extent, is admixed with the fresh solution obtained in a quantity which adjusts a supersaturated system, the capsulates obtainable as a result thereof, as well as their use with an encapsulated solution of a basic color former, which supplies a color by the reaction with acid reactants, in non-carbon paper.
