<p>Microcapsule, the walls of which comprise a resin that is obtained by reacting at least one aromatic alcohol or its ether or derivative with at least one aldehyde component containing at least 2C per molecule, and optionally at least one (meth)acrylate polymer, is claimed. Independent claims are included for: (1) a microcapsule dispersion comprising one or more microcapsules; (2) a copolymer comprising units derived from 2-acrylamido-2-methyl-propanesulfonic acid (AMPS) or its salts, and one or more (meth)acrylate comonomers from vinyl ester, (meth)acrylamide, urethane (meth)acrylate, 2-14C-alkenyl (meth)acrylates and their epoxides and aziridines, or alkylene glycol (meth)acrylates; and (3) preparing the microcapsule or microcapsule dispersion comprising reacting aromatic alcohol or its ether or derivative, aldehyde component and optionally (meth)acrylate polymer, optionally in the presence of core material, and then hardening the capsule by temperature increase. ACTIVITY : Antimicrobial; Fungicide; Herbicide; Insecticide. MECHANISM OF ACTION : None given.</p> |
