| 20100136472 | TONER COMPOSITIONS - Toner particles are provided which may, in embodiments, include a high molecular weight branched or cross-linked polyester to decrease image gloss and to increase toner elasticity to prevent surface additives impaction. In embodiments, the toner particles may have a core-shell configuration, with the high molecular weight polyester in the core, the shell, or both. | 06-03-2010 |
| 20100143839 | TONER PROCESS - The present disclosure provides processes for increasing the shelf life and stability of resin emulsions suitable for use in forming toner particles. In embodiments, the pH of the resin emulsion is monitored, and a base is added as needed to maintain the pH of the emulsion at from about 6.5 to about 8. Maintaining the pH at from about 6.5 to about 8 prevents the degradation of the resin in the emulsion, including its molecular weight. | 06-10-2010 |
| 20100159375 | TONERS CONTAINING POLYHEDRAL OLIGOMERIC SILSESQUIOXANES - Disclosed is a toner composition comprising toner particles which comprise a resin, an optional colorant, and a polyhedral oligomeric silsesquioxane compound. | 06-24-2010 |
| 20100159376 | TONERS CONTAINING POLYHEDRAL OLIGOMERIC SILSESQUIOXANES - Disclosed is a toner composition comprising toner particles which comprise (a) a resin having chemically bonded thereto a polyhedral oligomeric silsesquioxane, (b) and an optional colorant. | 06-24-2010 |
| 20100203439 | TONER COMPOSITIONS AND PROCESSES - Environmentally friendly toner particles are provided which may, in embodiments, include a bio-based amorphous polyester resin, optionally in combination with another amorphous resin and/or a crystalline resin. Toner particles may, in embodiments, have a core-shell configuration, with the shell formed of the bio-based amorphous polyester resin, the amorphous polyester resin, the crystalline polyester resin, or combinations thereof. | 08-12-2010 |
| 20100297546 | TONER COMPOSITIONS - Toner particles are provided which may, in embodiments, include a core and a shell. In embodiments, charge control agents may be co-emulsified with a resin utilized to form a shell. The shell may prevent a crystalline resin in the core from migrating to the toner surface. Inclusion of the charge control agent in the shell itself may provide the resulting toner particles with desirable charge characteristics and sensitivity to relative humidity. | 11-25-2010 |
| 20100330486 | Toner Compositions - A toner including at least one amorphous polyester, at least one crystalline polyester and at least one ester wax, wherein the linear polyester and the at least one ester wax have a difference in solubility parameter of from about 0.1 to about 1.7. | 12-30-2010 |
| 20110003243 | TONER COMPOSITIONS AND PROCESSES - Environmentally friendly toner particles are provided which may include a bio-based amorphous polyester resin, optionally in combination with another amorphous resin and/or a crystalline resin. Methods for providing these toners are also provided. | 01-06-2011 |
| 20110086302 | TONER COMPOSITIONS AND PROCESSES - An emulsion aggregation toner composition includes toner particles including: an unsaturated polymeric resin, such as amorphous resins, crystalline resins, and combinations thereof; an optional colorant; an optional wax; an optional coagulant; and an IR absorber. The use of an IR absorber may permit formation of color toners that have uniform gloss and crease properties, i.e., the IR absorbers may prevent gloss and crease differences between color and black toners. | 04-14-2011 |
| 20110086303 | TONER COMPOSITIONS AND PROCESSES - An emulsion aggregation toner composition includes toner particles including: an unsaturated polymeric resin, such as amorphous resins, crystalline resins, and combinations thereof; an optional colorant; an optional wax; an optional coagulant; and an IR absorber. The use of an IR absorber may permit formation of color toners that have uniform gloss and crease properties, i.e., the IR absorbers may prevent gloss and crease differences between color and black toners. | 04-14-2011 |
| 20110091803 | CURABLE TONER COMPOSITIONS AND PROCESSES - An emulsion aggregation toner composition includes toner particles including: an amorphous polyester resin; an optional crystalline resin; an optional colorant; an optional wax; an optional coagulant; and a polymeric or oligomeric hydroxy ketone photo initiator capable of initiating crosslinking of said polyester resin, wherein at least one of the amorphous polyester resin and the optional crystalline resin when present is unsaturated. | 04-21-2011 |
| 20110104607 | CHEMICAL TONER CONTAINING SUBLIMATION COLORANT FOR SECONDARY TRANSFER PROCESS - A chemical toner composition that includes at least one curable amorphous resin and at least one sublimation colorant. | 05-05-2011 |
| 20110104609 | SYNTHESIS AND EMULSIFICATION OF RESINS - The present disclosure provides processes for producing resins suitable for use in forming toner compositions. In embodiments, the processes described herein comprise formation of latexes, including latexes for use in toners, produced without use of solvents. | 05-05-2011 |
| 20110136056 | TONER COMPOSITIONS - The present disclosure relates to a toner including a core comprising at least one amorphous resin, at least one crystalline resin and one or more optional ingredients such as optional colorants, optional waxes, gels, and combinations thereof. The toner also includes a shell having an environmentally friendly charge control agent co-emulsified with at least one amorphous shell resin. | 06-09-2011 |
