Abstract
The instant disclosure describes methacrylate coated carrier resins with hydrophobic substituents for charge control and improved RH sensitivity.
Claims20
A carrier composition comprising a polymer coating resin comprised of at least one methacrylate monomer having a hydrophobic substituent, wherein the highest occupied molecular orbital (HOMO) of the methacrylate-containing polymer has greater than about 25% of the electron density of those molecular orbitals located on the hydrophobic substituent and less than about 75% of the electron density of those molecular orbitals on the carbonyl group of the methacrylate moiety.
A developer comprising:
- a carrier composition comprising a polymer coating resin containing at least one methacrylate monomer;
- a toner;
- and a toner surface additive,
- wherein the carrier composition further comprises a hydrophobic substituent, wherein the resin comprises the highest occupied molecular orbital (HOMO) electron density substantially located on the hydrophobic substituent, and wherein the HOMO electron density located on the carbonyl group of said at least one methacrylate monomer is reduced.
