Abstract
An improved in-situ polymerization method is provided for easily producing a good slurry of strong, dense, water-resistant and anti-hygroscopic microcapsules made of an amino resin of either of melamine-formaldehyde series or the ureaformaldehyde series, in a high concentration of microcapsules, and a low viscosity.
