Abstract: The present invention relates to a method for combining extra particulate additive with toner. The method includes mixing toner and extra particulate additive in a conical mixer having temperature control. The toner may contain polymeric material having a glass transition temperature (Tg) and the mixing may be carried out wherein the temperature of the mixture is maintained at a temperature less than Tg. The above method may also be applied to a toner formulation that has first undergone a rounding operation.

Abstract: Toner is rounded by vigorously mixing less than about 5 percent by weight of particulate silica to the total weight of a starting toner in a closed, recirculating air system. The starting toner contains at least about 4.5 percent by weight of the starting toner of a wax and additionally contains at least 5 percent by weight of the starting toner of a softening agent. The temperature during the mixing is no more than 13 degrees C. above the onset of the glass transition temperature of the starting toner. The final toner comprises rounded starting toner having particulate silica embedded during the mixing process.

Abstract: Toner particulates comprise a styrene/acrylic copolymer having a first aliphatic hydrocarbon wax incorporated therein during polyermization of the copolymer, and a second aliphatic hydrocarbon wax mixed with the copolymer.

Abstract: Toner particulates include a first resin comprising a cross-linked copolymer; a second resin comprising a non-cross-linked copolymer; and a wax comprising an ethylene propylene copolymer. The cross-linked copolymer is a copolymer other than the wax comprising an ethylene propylene copolymer and the non-cross-linked polymer is a copolymer other than the wax comprising an ethylene propylene copolymer.

Abstract: Polyether-urethane polymers, prepared from the reaction of specific molar ratios of diisocyanates with specific mixtures of polyetherdiols, glycols, triols and tetraols, and having 4-10 reactive isocyanate groups are further reacted with hydroxyalkyl acrylates through the free isocyanate functionality to provide polymers having from about 4-10 acrylates units per each mole unit of polyurethane chain. Such polymers when crosslinked under ultraviolet radiation in the presence of photosensitizers, specific reactive monofunctional acrylate solvents and multifunctional acrylate cross-linking agents cure without air inhibition to yield superior "wet look" finishes especially useful for coating metal, wood and floor tile.
