Coated carriers

A composition comprised of a core and thereover a polymer of (1) polystyrene/alkyl methacrylate/dialkylaminoethyl methacrylate, (2) polystyrene/alkyl methacrylate/alkyl hydrogen aminoethyl methacrylate, (3) polystyrene/alkyl acrylate/dialkylaminoethyl methacrylate, or (4) polystyrene/alkyl acrylate/alkyl hydrogen aminoethyl methacrylate.

A carrier comprised of a core and a polymer coating of (1) styrene/monoalkylaminoalkyl methacrylate or (2) styrene/dialkylaminoalkyl methacrylate.

A carrier comprised of a core and thereover a polymer of (1) methylmethacrylate and a monoalkyl aminoalkyl methacrylate, or (2) a polymer of methylmethacrylate and dialkylaminoalkyl methacrylate.

A toner including a mixture of first toner with high molecular weight wax, and second toner with a low molecular weight wax.

Toner composition and processes thereof

A carrier comprised of a core and thereover a polymer of styrene, an olefin and a dialkylaminoalkyl methacrylate.

A carrier comprised of a core and a polymer coating containing a quaternary ammonium salt functionality.

A toner composition comprised of a polyester resin with hydrophobic end groups, colorant, optional wax, optional charge additive, and optional surface additives.

Toner and developer compositions

A toner composition comprised of a polyester resin with hydrophobic end groups, pigment, optional wax, optional charge additive, and optional surface additives.

Unsaturated linear polymers have repeating units of a reaction product of a first monomer, a second monomer, a third monomer and optionally a fourth monomer. The linear polymers have a glass transition temperature ranging from about 52.degree. C. to about 61.degree. C. The first monomer should have a weight average molecular weight less than 200. The second monomer may be a dicarboxylic acid or diester which is different than the third monomer. A concentration of second residues of the polymer, derived from the second monomer, ranges from about 3 wt. % to about 15 wt. %, based on the total weight of the polymer. The third monomer is an aromatic dicarboxylic acid or an ester thereof. In the polymer, a concentration of third residues, derived from the third monomer, ranges from about 40 wt. % to about 55 wt. %, based on the total weight of the polymer. The fourth monomer is a diol having a higher molecular weight than the first monomer. In a process for preparing the inventive polymer, the first, second, third monomer (and optionally a fourth monomer) and/or a catalyst undergo transesterification to form the unsaturated, linear polymer.

Unsaturated polyesters

A low fix temperature toner having improved blocking performance comprises colorant and toner resin. The toner resin comprises the reaction product of (1) a diacid, diester or anhydride, (2) a diol and (3) a vinyl monomer compound having separate polyester and vinyl polymer domains with separate T.sub.g 's.

Unsaturated polyesters with vinyl side chains

A process for the preparation of a crosslinked polyester which comprises the reaction of a diol or a mixture of diols and a diacid, a mixture of diacids or their diesters and a polyhydric alcohol monomer to provide a polyhydroxy functional polyester resin precursor, and subsequently reacting said polyhydroxy functional polyester precursor resin with a dianhydride or diepoxy functional crosslinking component.
