摘要:
An encapsulated toner composition comprised of a core comprised of a polymer binder, a nonvolatile organic liquid, and magnetite; and wherein the core is encapsulated in a polyether-urea polymer shell.
摘要:
A toner having an amorphous resin, a crystalline resin, and a colorant, wherein the crystalline resin has a melting temperature of at least 70° C. and a recrystallization point of at least 47° C. exhibits improved document offset properties and improved heat cohesion. Annealing the toner further improves the heat cohesion and morphology of the toner.
摘要:
Exemplary embodiments provide compositions for erasable media and methods of forming polymers for erasable media. The method can include providing a first monomer, the first monomer including one or more alkoxylated bisphenols and adding at least one second monomer and a catalyst to the first monomer to form a mixture at a first temperature, the second monomer selected from the group consisting of an organic diacid, a dialkyl ester of the organic diacid, and combinations thereof. The method can also include melt condensing the mixture by increasing the temperature from the first temperature to a second temperature over a first amount of time to form one or more polymers, wherein the one or more polymers has an acid value in the range of about 0.1 mg-KOH to about 12 mg-KOH.
摘要:
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.
摘要:
A toner composition includes a reactive resin substantially free of cross linking, a wax, and a colorant. The reactive resin can include reactive epoxy and carboxylic acid functional groups.
