In one embodiment, the primary capsule comprises a silica capsule, a zirconia capsule, a titania capsule or combinations thereof. In one embodiment, the polymer latex particles have an average particle size in the range of from 50 nm to 1000 nm and the primary capsule has an average particle size in the range of from 1 pm to 100 pm. In one embodiment, the heterocoagulating step is carried out in the presence of at least two different surfactants comprising at least one cationic surfactant and at least one anionic surfactant. In one embodiment, the at least two different surfactants are independently selected from the group consisting of a primary amine surfactant, a secondary amine surfactant, a tertiary amine surfactant, a quaternary amine surfactant, cetyl trimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS), carboxylic acid salt, sulfonic acid salt, phosphoric acid ester, alcohol sulfate, alkylbenzene sulfonate or combinations thereof. According to another aspect, there is provided a hybrid capsule comprising a primary capsule having a shell; and an organic polymer coating layer over the shell of the primary capsule. In one embodiment, the hybrid capsule is an organic-inorganic capsule and the primary capsule is an inorganic capsule. In one embodiment, the shell of the primary capsule is substantially hermetically sealed by the polymer coating layer. In one embodiment, the hybrid capsule is micron- or submicron-sized. In one embodiment, the hybrid capsule is substantially resistant to breaking under scanning electron microscopy (SEM) vacuum conditions.
