摘要：
A microcapsule enclosing a color-former solution for a pressure-sensitive recording paper is prepared by a process in which a water-soluble cationic urea resin and at least one of prepolymer selected from the group consisting of melamine-formaldehyde prepolymer, urea-formaldehyde prepolymer and melamine-urea-formaldehyde prepolymer are polycondensed on the surface of a dispersed solvent droplet containing a color-former in the presence of an anionic surfactant, while causing complex-coacervation between the water-soluble cationic urea resin and the anionic surfactant.
