摘要:
Ultra low melt toner compositions with improved non-additive heat cohesion are disclosed. These toner compositions include toner particles comprising amorphous resins containing at least one unsaturated moiety, and when the toner particles are surface treated with a peroxy compound and optionally with a peroxy promoter compound, the surface of the toner particles is cross-linked to form a thin, robust shell. Processes for preparing the toner compositions are also described.
摘要:
A preparation method of carbon modified filler is provided. The method is: putting the fillers into the reaction zone of a reactor, starting the first heating-up to 400-500° C. under the protective atmosphere at first, then introducing hydrogen after the heating-up; starting the second heating-up to 600-1200° C. after introducing hydrogen and simultaneously introducing the mixture of hydrogen and carbon source gas, keeping at the terminal temperature for 0.1-5 hours, introducing nitrogen and stopping heating after the reaction, cooling, and then getting the carbon modified filler. The above method can obtain a friction material with good mechanical properties, excellent friction and wear performances, stable friction coefficient at high temperature, good braking force and no heat recession.
摘要:
A transfer printing method including applying a curable sublimation toner having at least one curable component and at least one sublimation colorant in a desired pattern onto a transfer substrate to form an image on the transfer substrate at a first temperature which is below the sublimation temperature of the sublimation colorant; wherein the curable sublimation toner is a conventional toner or a chemical toner; and wherein the curable sublimation toner includes at least one curable amorphous resin and optionally, a crystalline resin; curing the image on the transfer substrate; and optionally, bringing the transfer substrate into contact with a final image-receiving substrate, optionally applying pressure, and heating to a second temperature which is sufficient to cause the sublimation colorant to sublime and form a permanent image on the final image-receiving substrate.

A curable sublimation marking material including at least one curable component and at least one sublimation colorant. Also disclosed is a transfer printing method including applying a curable sublimation marking material in a desired pattern onto a transfer substrate to form an image on the transfer substrate at a first temperature which is below the sublimation temperature of the sublimation colorant; wherein the curable sublimation marking material comprises at least one curable component and at least one sublimation colorant; curing the image on the transfer substrate; and optionally, bringing the transfer substrate into contact with a final image-receiving substrate, optionally applying pressure, and heating to a second temperature which is sufficient to cause the sublimation colorant to sublime and form a permanent image on the final image-receiving substrate.
摘要:
An improved polycondensation method for bio-based polyesters synthesized from pre-formed macromers and the corresponding compositions, which are useful for producing binder polymers for imaging applications such as emulsion-aggregation (EA) toner.
摘要:
Toner particles are provided which may, in embodiments, include a core and a shell formed in situ. The resins utilized to form the core, the shell, or both, may be contacted with a water soluble initiator. The resin, in embodiments present in the shell, cross-links at a temperature near the temperature for coalescence, and may prevent a crystalline resin in the core from migrating to the toner surface.
摘要:
Disclosed is a polyester resin comprising the polycondensation product of (a) at least one diacid, acid ester, or diester; and (b) at least one diol; wherein either (i) at least one diacid, acid ester, or diester comprises a rosin diacid, rosin acid ester, or rosin diester; or (ii) at least one diol comprises a rosin diol. Also disclosed is a toner composition comprising particles which comprise the disclosed polyester resin and an optional colorant.
