Process of making microcapsules as carriers for encapsulated solid or liquid color components in color reaction papers, wherein particles of finely divided solid substances are incorporated in the capsule walls during the formation of the capsules by chemical reaction from a film forming component dissolved in the dispersed phase of a liquid dispersion system, which contains dissolved in its continuous phase a low-molecular weight reactant for the film-forming component; also contained in the dispersion system are said solid particles to be incorporated into the walls of the microcapsules. Very high percentages of solid particles, i.e., considerably higher than 100 percent calculated on the weight of the capsule wall, can thus be incorporated into the latter thereby increasing the resistance of the walls to mechanical stress far above the limit of known microcapsules.
