Abstract
A coated powder comprising a transition metal or compound thereof prepared by the process which comprises coating the surface of a powdered transition metal or compound there with a free radical polymerizable monomer having an e value of (-)0.8 to (+)0.8 and then subjecting the resulting coated powder to free-radical polymerization conditions.
Claims6
A toner powder capable of developing permanent visible images from latent electrostatic images comprising a thermoplastic resin and a coated powder comprising a transition metal or compound thereof which is coated with a polymer made from a free radical polymerizable monomer having an E value of (-)0.8 to (+)0.8 by in situ polymerization.
