Microcapsules containing a hydrophobic, volatile core substance and their production |
摘要 |
Disclosed herein are microcapsules containing a hydrophobic, volatile substance as the core substance, a wall membrane of the microcapsule comprising a polymer made by interfacial polymerization of a polyvalent isocyanate with a water-soluble cationic urea resin and/or a prepolymer of aminoresin, and a resin made by polycondensing the water-soluble cationic urea resin with the prepolymer of aminoresin in the presence of a low-molecular anionic surfactant, and a process for producing the microcapsules.
