Abstract

(Meth)acrylate resins of at least one bio-based (meth)acrylate monomer, where the monomer includes a rosin or isosorbide moiety obtained from natural sources, can be used in toner, carrier coating or both.

Claims

1. A carrier composition comprising a core and a coating thereon, wherein said coating comprises a resin comprising a bio-based acrylate or methacrylate monomer, and optionally a styrene, acrylic or methacrylic monomer, wherein said bio-based acrylate or methacrylate monomer comprises an isosorbide moiety.

2. The carrier composition of claim 1, wherein the coating further comprises a conductive material.

3. The carrier composition of claim 1, wherein the coating further comprises a colorant.

4. The carrier composition of claim 1, wherein the carrier coating resin comprises a C/O ratio greater than 2.5.
