摘要: A process for the production of aqueous suspensions containing from 35 to 60% by weight of microcapsules by interfacial polyaddition from polyisocyanates and H-active compounds, wherein(a) an isocyanaurate-modified aliphatic polyisocyanate is used as the polyisocyanate, and(b) the suspension is adjusted to a pH-value of .ltoreq.7 after the polyaddition reaction,which microcapsules optimally contain dye precursors and can be used for the production of completely or partly coated copying systems by the rotogravure or flexograph processes.
