Emulsifier for microcapsules, 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.
