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.
摘要:
Polymer particles comprising a cross-linked polymer core and a linear non-cross-linked polymer shell may be formed by emulsion polymerization. The polymer particles may be used in forming toner.
摘要:
A toner composition includes a resin substantially free of cross linking and having a weight average molecular weight of from about 50,000 to about 1,000,000, a wax, a colorant, and a coagulant.
摘要:
Toner compositions include a non cross linked resin; a cross linked resin or gel; a wax; and a colorant. Processes for preparing a toner include mixing a non-cross linked resin and a cross-linked resin or gel in the presence of a wax, a colorant, and a coagulant to provide toner size aggregates; adding additional non-cross linked latex to the formed aggregates thereby providing a shell over the formed aggregates; heating the shell covered aggregates to form toner; and, optionally, isolating the toner.
摘要:
A toner is disclosed that includes a toner binder of a styrene/acrylate resin containing carboxylic acid substituents and epoxy substituents, and optionally a colorant and/or wax. The carboxylic acid substituents act as a curing agent and react with the epoxy substituents, causing rapid crosslinking of the toner. Curing occurs during the fusing process and at a temperature greater than 100° C.
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 0.5166% 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.
摘要:
A toner composition includes core toner particles and a shell formed over the core toner particles. The core toner particles include a resin substantially free of cross linking, an optional cross linked resin, a polyester resin, and a colorant. The shell includes a resin containing charge control agent recurring units.
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:
A toner includes particles of a resin, an optional colorant, a first wax and a second wax, where the toner particles are prepared by an emulsion aggregation process. Additional waxes can also be added for different properties.
摘要:
A toner including particles of a resin, an optional colorant, and a crystalline wax, where the crystalline wax is selected from aliphatic polar amide functionalized waxes, carboxylic acid-terminated polyethylene waxes, aliphatic waxes consisting of esters of hydroxylated unsaturated fatty acids, high acid waxes, and mixtures thereof, is prepared by an emulsion aggregation process.
