Abstract
In an image recording method, the toner particles are preferably obtained by microencapsulation techniques. The techniques form a dispersion of a core material in a medium containing the shell material. The shell material is deposited upon the surface of the core material to form the capsules. The capsules are hardened to prevent their agglomeration. The capsules are then recovered. Preferably, the continuous phase is normally a solution of the shell material. The core structure advantageously comprises a colorant and at least one additive, such as, for example, a resin binder.
