Non-bisphenol-A emulsion aggregation toner and process

A toner composition comprising:

• a core;
• at least one shell disposed thereover;
• wherein the core comprises at least one amorphous polyester resin, at least one crystalline polyester resin, wherein the crystalline polyester resin comprises an acid monomer comprising at least one methylene group and an alcohol monomer comprising at least one methylene group, wherein said acid and alcohol monomers together comprise 14 or fewer methylene groups;
• at least one styrene acrylate copolymer, an optional wax, and an optional colorant;
• wherein the shell comprises at least one styrene acrylate copolymer and an optional wax;
• and
• wherein the amorphous polyester resin comprises a rosin monomer content of from about 10 to about 25 percent rosin monomer based upon the total amount of monomer comprising the amorphous polyester resin.

A toner process comprising:

• contacting an amorphous polyester resin;
• a crystalline polyester resin wherein the crystalline polyester resin comprises an acid monomer comprising at least one methylene group and an alcohol monomer comprising at least one methylene group, wherein said acid and alcohol monomers together comprise 14 or fewer methylene groups;
• a styrene acrylate copolymer;
• an optional wax;
• an optional colorant;
• and an optional aggregating agent;
• wherein the amorphous polyester resin comprises a rosin monomer content of from about 10 to about 25 percent rosin monomer based upon the total amount of monomer comprising the amorphous polyester resin;
• heating to form aggregated toner particles;
• optionally, adding a shell resin to the aggregated toner particles, and heating to a further elevated temperature to coalesce the particles;
• and
• recovering the toner particles.
