摘要:
A toner process involving the heating a mixture of an acicular magnetite dispersion, a colorant dispersion, a wax dispersion, a first latex containing a crosslinked resin, and a second latex containing a resin free of crosslinking in the presence of a coagulant to provide aggregates, stabilizing the aggregates with a silicate salt dissolved in a base, and further heating the aggregates to provide coalesced toner particles.
摘要:
A toner includes particles of a resin, an optional colorant, and an acid-containing crystalline polymeric wax, where the acid-containing crystalline wax is selected from carboxylic acid-terminated polyethylene waxes, high acid waxes, and mixtures thereof, and where the toner particles are prepared by an emulsion aggregation process.
摘要:
Processes for producing emulsion aggregation toners are provided. In embodiments, methods of the present disclosure may be utilized to produce toners suitable for low melt applications, including use in flexible packaging applications, where low pile height is desired for low cost and flexibility. In embodiments, the EA toners may be prepared by optimizing the particle size of the emulsion, the choice of and amount of aggregating agent utilized, and the solids content of the emulsion.

摘要:
Provided are a latex process and a toner process, both of which include the preparation of a latex having weight average molecular weight of from about 12×103 to about 24×103. The latex is manufactured under monomer-starved polymerization condition such as monomer feeding rate equal to or less than 0.516% per minute by weight of the monomer(s) to be fed. The toners prepared according to the present disclosure have gained improved properties such as gloss, fusing performance, crease performance, stripping performance, document offset, vinyl offset, and parent charging etc.
