Abstract: A low melt toner resin with low minimum fix temperature and wide fusing latitude contains a linear portion and a cross-linked portion containing high density cross-linked microgel particles, but substantially no low density cross-linked polymer. The resin may be formed by reactive melt mixing.

Abstract: A process for the preparation of toner compositions comprising: forming a mixture comprised of at least one free radical reactive monomer, a colorant, a stabilizer compound containing a stable free radical reactive group, and a liquid vehicle; and heating the mixture from about 75 to about 200 DEG C to effect polymerization of said monomer, wherein there results stabilized core resin particles containing said colorant and wherein said stabilized core particles are stabilized by said stable free radical reactive stabilizer compounds being bonded directly to the core particles.

Abstract: Ink jet inks and liquid developers are disclosed which contain coloured particles comprising hydrophilic silica particles, to the surfaces of which dyes are covalently bonded through silane coupling agents. The ink jet inks generally comprise a liquid medium and a plurality of the coloured silica particles. The liquid developers generally comprise a liquid medium, a resin, a pluraltiy of the coloured silica particles, and a charge-control agent. The particles are prepared by a process which comprises reacting hydrophilic silica particles with a silane coupling agent in the absence of water to form particles having covalently attached thereto coupling agents, followed by reacting a dye with the coupling agent attached to the silica particles.
