Abstract: A method for modifying the surface of the microcapsule consisting of an outer layer composed of a urea-formaldehyde copolymer, a melamine-formaldehyde copolymer or a urea-melamine-formaldehyde terpolymer and an inner phase composed of hydrophobic organic components, the method comprises contacting the microcapsule with a water-immiscible organic solvent and at least one member selected from the group of compound of general formula (I) ##STR1## wherein R is an alkyl group having 8 to 22 carbon atoms; x and y are each a whole number not less than 0 and their sum is a whole number of not more than 60, provided that x and y cannot be simultaneously equal to 0.
