The invention describes a core shell microcapsule wherein the capsule shell is an interfacial copolymer formed of a modified polysaccharide free radical cross-linked with a multifunctional (meth)acrylate. The polysaccharide is hydrophobically modified with an adduct containing at least one unsaturated bond. The modification imparts hydrophobic character to the polysaccharide to act as an emulsifier, driving the modified polysaccharide to an oil-water interface of an encapsulation emulsion described, and creates an active bonding site for free-radical polymerization between the polysaccharide and multifunctional (meth)acrylate, thereby forming a microcapsule shell surrounding the core material.
