Process for encapsulating dissolved reactants colored of color reaction systems, the capsules obtained subsequently as well as use in color-reaction papers.

摘要

Method for encapsulating a present solution in an aqueous emulsion of reactants colored of color reaction systems by the customary microencapsulation, in which the color reactant is first dissolved in a solvent and the obtained solution was added with rapid mixing a nonsolvent , which in any case dissolves insignificantly the color reactant, in an amount to adjust a supersaturated solution, the supersaturated solution is emulsified immediately in the aqueous phase with rapid mixing and immediately after encapsulation is performed, wherein as solvent using a C1-C8 alkyl ester of vegetable oil.
