Disclosed are processes for the preparation of rosin diols accomplished by the reaction of a rosin acid with a glycerine carbonate in the presence of a catalyst, and subsequently where the rosin diol can be reacted with a diacid to generate an amorphous polyester resin.

Polyester processes

The present embodiments disclose processes for preparing a polyester latex containing an amount of residual organic solvent which is less than 100 ppm by weight of the total weight of the polyester latex.

Steam injection process for preparing polyester latex and apparatus thereof

The present disclosure provides a polyester toner resin comprising a natural phenol used in manufacturing a toner for imaging devices.

Biophenols for polyester toner resins

A toner includes a polymeric resin, optionally a colorant, and a small molecule crystalline diester having an aromatic core and a molecular weight less than 1,000 g/mol. The polymeric resin may be an amorphous resin and a mixture of the amorphous resin and the crystalline aromatic diester may be characterized by a reduction in glass transition temperature from that of the resin and by the lack of a significant solid to liquid phase transition peak for the small molecule compound as determined by differential scanning calorimetry, the enthalpy of fusion for the small molecule compound in the mixture being measured to be less than 10% of the enthalpy of fusion of the compound in pure form. Furthermore, the toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner.

Super low melt toner having crystalline diesters with an aromatic core

Disclosed is a toner that includes a mixture of a bio-based amorphous polyester resin, a crystalline polyester resin, and a colorant.

Toner compositions of biodegradable amorphous polyester resins

A polyester resin toner-forming composition containing a biopolyol is described. The biopolyol can enhance branching, crosslinking or both.

Polyester resin comprising a biopolyol

Embodiments include a toner having a polyester resin derived from diacids and diesters, in combination with at least one diol, in embodiments a cycloaliphatic diol, an optional crystalline resin, an optional colorant, and an optional wax.

Polyester resin containing toner

The toner includes emulsion aggregation toner particles having a core and a shell. The core includes binder including a first non-crosslinked styrene acrylate polymer and a crosslinked styrene acrylate polymer, at least one colorant, at least one wax, and aluminized silica. The shell includes a second non-crosslinked styrene acrylate polymer that is preferably the same as the non-crosslinked styrene acrylate polymer of the core. The aluminized silica is advantageously used as a coagulant in the emulsion aggregation formation of the toner. A developer containing the toner and a method of forming an image using the toner are also described.

Emulsion aggregation toner incorporating aluminized silica as a coagulating agent

There is disclosed a coating composition including water, a solvent, a grafted elastomer composed of a polyorganosiloxane bonded to a fluoroelastomer, and a liquid which forms an azeotropic mixture with the water, wherein the azeotropic mixture of the water and the liquid restrains a viscosity increase in the coating composition over time.
