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.

First claim

1 . A resin comprising a bio-based (meth)acrylate monomer, and optionally a styrene, acrylic or methacrylic monomer, wherein said bio-based (meth)acrylate monomer comprises a rosin or an isosorbide moiety.

2 . The resin of claim 1 , wherein the rosin is a gum rosin, wood rosin or tall-oil rosin.

3 . The resin of claim 1 , wherein the bio-based (meth) acrylate monomer comprises isosorbide.

4 . The resin of claim 1 , wherein the acrylic monomer comprises acryloyl chloride(2-propenoyl chloride) or methacryloyl chloride(2-methylprop-2-enoyl chloride).

5 . The resin of claim 1 , wherein the bio-based (meth)acrylate monomer is selected from the group consisting of isosorbide diacrylate, isosorbide acrylate, isosorbide methacrylate and isosorbide dimethacrylate.

6 . The resin of claim 1 , wherein the bio-based (meth)acrylate monomer comprises a rosin.

7 . The resin of claim 1 , wherein the rosin is selected from the group consisting of abietic acid, palustric acid, dehydroabietic acid, neo-abietic acid, levopimaric acid, pimaric acid, sandaracopimaric acid, iso-pimaric acid, hydrogenated rosin acid and combinations thereof.

8 . The resin of claim 1 , wherein the acrylic monomer comprises an epoxy acrylate or an epoxy methacrylate.

9 . The resin of claim 1 , wherein the acrylic monomer comprises a glycidyl methacrylate.

10 . The resin of claim 1 , wherein the bio-based (meth)acrylate monomer comprises an abietic-(meth)acrylate.

11 . A toner particle comprising the resin of claim 1 .

12 . The toner particle of claim 11 , further comprising at least one of a second resin, a colorant or a wax.

13 . The toner particle of claim 11 , further comprising a shell.

14 . The toner particle of claim 13 , wherein said shell comprises a colorant.

15 . A shell resin comprising the resin of claim 1 .

16 . A carrier composition comprising a core and a coating thereon comprising the resin of claim 1 .

17 . The carrier composition of claim 16 , wherein the coating comprises a conductive material.

18 . The carrier composition of claim 16 , wherein the coating comprises a colorant.

19 . A developer comprising toner particles and optionally a carrier comprising a core comprising a coating, wherein said toner particles, said coating or both comprise the resin of claim 1 .

20 . The developer of claim 19 , wherein the toner particles are emulsion aggregation toner particles.
