The proposal is made for a process for the preparation of a minisuspoemulsion of submicron core/shell particles, whereinthe starting material is a suspoemulsion of a first disperse liquid phase I in a second continuous liquid phase II, whichcomprises, in the first disperse liquid phase I, submicron particles of a solid C forming the core, anda precursor substance PS for the shell dissolved in molecularly disperse form and, if appropriate, a reactant R, and whereinthe submicron core/shell particles CS are prepared in the first disperse liquid phase I of the suspoemulsion by chemical or physical conversion of the precursor substance PS for the shell.
