Abstract

DISPERSãO DE MICROCáPSULA, PROCESSO PARA A PREPARAçãO DE UMA DISPERSãO DE MICROCáPSULA, E, MICROCáPSULAS. A presente invenção refere-se a dispersões de microcápsulas, que compreendem mierocápsulas em um solvente hidrofóbico, em que as microcápsulas possuem um núcleo de cápsula, que compreende uma substância orgânica solúvel em água em solução em um solvente hidrofilico, e uma casca de cápsula, obteníveis através de a) poliadição interfacial de pelo menos um di-, oligo- e/ou poliisocianato com pelo menos um reagente, que porta pelo menos um grupo reativo a isocianato e b) pós- tratamento subseqúente das microcápsulas do produto primário com pelo menos um composto selecionado a partir do grupo, que consiste de aminas, álcoois e aminoálcoois tendo um peso molecular de pelo menos 150 g/mol e c) se apropriado, pós-tratamento subseqúente com pelo menos um reagente de pós-tratamento adicional.
