Abstract
Microcapsules, of which the wall material was made of calcium silicate , with a core material of thermal-sensitive pigment were prepared by i nterfacial reaction in multiple dispersion. The microcapsules obtained were characterized as follows. The shape was observed with a low-vacu um scanning electron microscope (LVSEM). The size was directly measure d from the LVSEM micrgraphs. The yield was evaluated by the total mass balance of the materials involved. The color was observed by the nake d eye. Effects of the concentration of stabilizer and the impeller spe eds on the mean particle size and the yield were investigated.
