The present invention is directed to microcapsules having polymeric shells that possess blocking groups (e.g., amine-blocking groups), the removal or cleavage of which act to initiate release of the core material therein, or increase the rate at which such core material is released. The present invention is further directed to the formulation of said microcapsules in aqueous dispersions, to the preparation of said microcapsules, and to the use of such microcapsules and dispersions thereof.
                            本发明涉及具有聚合物壳的微胶囊,其具有阻塞基团(例如,胺阻塞基团),其去除或裂解作用于启动其中核心材料的释放,或增加这种核心材料释放的速率。本发明进一步涉及在
水分散体系中制备这些微胶囊的配方,制备这些微胶囊的方法,以及这些微胶囊和其分散体系的用途。
