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.

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.

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.

Methods of using a toner as a printable adhesive are provided. In embodiments, a method of adhering substrates is provided which comprises disposing a cold pressure fix toner comprising a phase change material on a first substrate via xerography to form an unfused layer of the cold pressure fix toner on the first substrate; placing a second substrate on the unfused layer of the cold pressure fix toner; and subjecting the cold pressure fix toner to a pressure to form a bonded article comprising the first substrate, an adhesive layer formed from the cold pressure fix toner, and the second substrate. Methods of applying an adhesive to a substrate and bonded articles are also provided.

Disclosed herein are methods of electrostatically printing a cyclodextrin composition on a substrate, the method including forming an electrostatically printable composition comprising a polymer and one or more cyclodextrins, one or more cyclodextrin inclusion complexes, or a combination thereof, and electrostatically printing the composition on a substrate. Also described are electrostatically printable compositions, methods of making the compositions, printing systems employing the compositions, substrates having the composition electrostatically printed thereon, laminates thereof, and uses of the printed substrates and laminates.
