Abstract

MICROCáPSULAS TENDO LIBERAçãO ATIVADA DE MATERIAL DE NúCLEO DENTRO DELAS. A presente invenção refere-se às microcápsulas tendo invólucros poliméricos que possuem grupos de bloqueio (por exemplo, grupos de bloqueio de amina), a remoção ou clivagem destes agem para iniciara liberação do material de núcleo neles, ou aumenta a taxa na qual tal material de núcleo é liberado. A presente invenção é também direcionada à formulação das ditas microcápsulas em dispersões aquosas, á preparação das ditas microcápsulas e ao uso de tais microcápsulas e suas dispersões.
