The present disclosure is drawn to methods and compositions directed at encapsulated pigments. As such, an encapsulated pigment can comprise a pigment and a polymer encapsulating the pigment, where the polymer comprises a monomer and a RAFT reagent. Additionally, a method of encapsulating pigments can comprise dispersing a pigment in an aqueous solution to form a pigment dispersion, adding a monomer to the pigment dispersion, adding a RAFT reagent to the pigment dispersion, and polymerizing the monomer using the RAFT reagent in the presence of the pigment to form an encapsulated pigment. Further, the present disclosure provides ink-jet inks comprising the encapsulated pigments.
