반응 단계
A process for manufacturing microcapsules by dissolving or dispersing microcapsule contents in an aqueous solution of acrylic acid-methacrylic acid copolymer and/or acrylic acid-itaconic acid copolymer, then polymerizing urea and/or melamine and formaldehyde in the solution or dispersion adjusted to pH 2.5~6.0, and forming film of urea-formaldehyde copolymer, melamine-formaldehyde copolymer, or urea-melamine-formaldehyde copolymer around capusle contents.
