EMULSIFIER FOR MICROCAPUSLES, MICROCAPSULES USING SAID EMULSIFIER AND PROCESS FOR PRODUCING SUCH MICROCAPSULES, AND NON-CARBON PRESSURE-SENSITIVE COPYING PAPER USING SAID MICROCAPSULES

摘要

Disclosed in this invention are an emulsifier for producing microcapsules, containing as active principle a water-soluble polymer the emulsifier being composed of benzyl (meth)acrylate and/or diisobutylene, styrene and maleic anhydride, microcapsules using the emulsifier, a process for producing the microcapsules, and a non-carbon pressure-sensitive copying paper using the microcapsules.
