Crash cooling method to prepare toner

The present disclosure relates generally to a method to make a chemically prepared toner that employs a crash cooling process. In the crash cooling process, hot toner slurry is added to an external reactor containing a coolant comprised of previously cooled toner slurry in combination with cooled de-ionized water. The previously cooled toner slurry found in the coolant has the same toner composition as the incoming hot toner slurry. Also, the amount of the coolant in the external reactor is equivalent to the amount of incoming hot toner slurry. Polyester toners and polyester core shell toners having a borax coupling agent between the toner core and toner shell made from this crash cooling process results in an improvement to the toner performance especially a decrease in the overall toner usage.

Crash cooling method to prepare toner

The present disclosure relates generally to a method to make a chemically prepared toner that employs a crash cooling process. In the crash cooling process, an amount of hot toner slurry is added to an external reactor holding an amount of chilled cooling water, wherein the temperature of the chilled cooling water in the external reactor is from about 8 C. to about 25 C. The amount of the chilled cooling water in the external reactor is about 10% to about 40% lower compared to the amount of the added hot toner slurry. Toner prepared using this crash cooling method is cooled at a rate of less than 0.8 C./min. Polyester toners and polyester core shell toners having a borax coupling agent between the toner core and toner shell made from this crash cooling processes using less water results in an improvement to the toner's print density and usage efficiency.

Cold pressure fix toner compositions based on small molecule crystalline and amorphous organic compound mixtures

A cold pressure fix toner composition includes at least one C.sub.16 to C.sub.80 crystalline organic material having a melting point in a range from about 30 C. to about 130 C. and at least one C.sub.16 to C.sub.80 amorphous organic material having a Tg of from about 30 C. to about 70 C. A method of cold pressure fix toner application includes providing the cold pressure fix toner composition, disposing the cold pressure fix toner composition on a substrate and applying pressure to the disposed composition on the substrate under cold pressure fixing conditions. The cold pressure fix toner compositions can be formed into latexes.

Crash cooling method to prepare toner

The present disclosure relates generally to a method to make a chemically prepared toner that employs a crash cooling process. In particular, the crash cooling process involves the addition of a toner slurry having a temperature between 70 C. and 90 C. to an equivalent amount of cold water having a temperature between 5 C. and 20 C. Polyester and styrene acrylic toners as well as polyester core shell toners having a borax coupling agent between the toner core and toner shell made from this cooling process results in an improvement to the amount of toner waste, thereby achieving a higher toner usage efficiency for an electrophotographic printing system.
