MICROCAPSULE AND HEAT SENSITIVE RECORDING MATERIAL USING THE SAME

摘要

PURPOSE:To provide microcapsules excellent in material passing ability under heating as well as material isolating performance at ordinary temp. and a heat sensitive recording material using the microcapsules. CONSTITUTION:When polyisocyanate is allowed to react with water and at least one of polyamine and polyhydric alcohol to obtain microcapsules, part of the polyisocyanate is previously allowed to react with monohydric alcohol. The objective microcapsules are provided and a heat sensitive recording material using the microcapsules is also provided.
