A composition which comprises at least one particle, the or each particle comprising an active substance-containing solid or liquid core encapsulated by a (co)polymer, which composition is obtained by treating at least one solid or liquid active substance-containing particle by adsorbing thereon at least one amphipathic compound and, if the amphipathic compound is not itself capable of acting as an initiator in cationic polymerization, activating the amphipathic compound with a Bronsted or Lewis acid so that it can function as an initiator in cationic polymerization; and encapsulating the at least one treated particle by the in situ (co)polymerization thereon, in a non-aqueous medium, of at least one cationically polymerizable monomer or prepolymer.
