Encapsulated magnetic particles, pigments and carbon black, compositions and methods related thereto.

A high affinity of the particle comprises a carrier, a particle the magnetic particles, the pigment or carbon black of colouring. Envelope's particle is suitable for printing ink and a magnetic recording system, such as recording tape and obtained from and magnetic separation plate. Envelope's particle comprises a a coating, wherein the coating is a ionomer or oil, such as soy oil, or the ionomer and oil mixture, and dispensable thixotropic agent and/or adhesive resin is formed. A method for preparing the particle the method, avoided is easy to volatilize the use of organic solvent, and provides a printing ink and coating composition, avoided is easy to volatilize use of the organic solvent. The envelope's simply tinting pigment or carbon black dispersing carrier in need of the ink and much easily, and does not need to the expensive cleaning technology.
