摘要:
A process including blending a latex emulsion of resin, water, and an ionic surfactant, a colorant dispersion comprised of a colorant, water, and an ionic surfactant; and a wax dispersion comprised of wax, water and an ionic surfactant, heating the resulting mixture in the presence of coagulants, one of which is a source of calcium ions, which heating is below about the glass transition temperature (Tg) of the latex resin and subsequently heating above about the glass transition temperature (Tg) of the latex resin.
摘要:
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.
摘要:
Toner particles are provided which may, in embodiments, include a core possessing an amorphous resin and a crystalline resin in combination with a colorant, optional wax, and optional other additives, and a shell over the core including a branched amorphous resin. The branched resin in the shell may prevent the crystalline resin from migrating to the toner surface.

摘要:
A toner includes binder of amorphous polymer material, such as an amorphous polyester material, and a crystalline polymer material, such as a crystalline polyester material, wherein the amorphous polymer material has an acid number that is greater than an acid number of the crystalline polymer material. Further, the toner may have a minimum fusing temperature of from about 75° C. to about 150° C. and a relative humidity sensitivity of from about 0.5 to about 10. A method of making toner particles is also indicated.

摘要:
A toner composition comprising a binder, colorant, and a charge control surface additive mixture comprising a mixture of a first titanium dioxide possessing a first conductivity and a second titanium dioxide possessing a second conductivity and which second conductivity is dissimilar than the first conductivity; wherein the mixture of the first titanium dioxide and the second titanium dioxide is selected in a ratio sufficient to impart a selected triboelectric charging characteristic to the toner composition.
摘要:
Various venturi configurations are described that are particularly significant for ballistic aerosol marking (BAM) applications. The specific venturi geometries enable the printing of lines having sharp edges and particular widths, using relatively low pressures.
