METHOD FOR PRODUCING MICROCAPSULES HAVING IMPROVED WALL CHARACTERISTICS |
摘要 |
A process for forming microcapsules having substantially impermeable microcapsule walls comprising the steps of: forming an emulsion of an internal phase in a continuous aqueous phase, the internal phase including a photosensitive composition and a polyvalent isocyanate, the continuous aqueous phase including a sulfonated polystyrene, at least one of the internal phase or the continuous aqueous phase further including a hydrophilic polymer; and enwrapping particles of the internal phase in an amine-formaldehyde condensation product produced by in situ condensation of an amine and formaldehyde is disclosed. |
