This present application relates to microcapsules or compositions containing microcapsules wherein the microcapsules comprise a polymerizable lactamic copolymer. More particularly, certain aspects are directed to the use of polymerizable lactamic copolymers in the formation of coatings on microencapsulated particles. These polymerizable lactamic copolymers can result in surface modified microencapsulated particles that may be anionic, non-ionic, or cationic.
