Abstract
PURPOSE:To raise the stability of emulsified liquid when capsule is formed for preventing the coalescence of oily liquid or the floating of the oily liquid to the surface by adding a multivalent isocyanate, multivalent isochiocyanate, or the prepolymer of these to the hydrophobic oily liquid to be capsulated. CONSTITUTION:A melamine-formaldehyde resin wall is formed on the surfaces of a hydrophobic oily liquid by polymerizing melamine and formaldehyde or the prepolymer of these in the presence of a water-soluble macromolecular compound. In this case, a multivalent isocyanate, a multivalent isothiocyanate, or the prepolymer of these are added to the hydrophobic oily liquid in order to raise the stability of emulsified liquid obtained.
