Abstract:
The present disclosure is directed to a composition including a polyvinyl butyral represented by the following formula: wherein A, B and C represent a proportion of corresponding repeat units expressed as a weight percent, wherein each repeat unit is randomly distributed along a polymer chain and wherein the sum of A, B and C is about 100 weight percent; a poly(melamine-co-formaldehyde) based polymer and an anhydride. Devices coated with the composition and cured films formed from the composition comprising conductive features are also provided.
Abstract:
The present disclosure provides processes for producing toners by emulsion aggregation where the resulting toner particles have high pigment loadings and desired circularity. The methods include adding a metal, in embodiments a metal salt, at the beginning of coalescence, which surprisingly speeds the coalescence process and produces toner particles having a desired size and circularity for use in electrophotographic imaging systems.
Abstract:
The disclosure provides sustainable toner particles of from about 180 nm to about 250 nm in a sustainable toner composition having a hot offset temperature of from about 190° C. to about 220° C.
Abstract:
A high silver content nanosilver conductive ink includes at least about 65% weight of silver nanoparticles, a non-polar organic solvent and, a polymer binder. The conductive ink has a has a conductivity of from about 1.0×104 (S/cm) to about 4.0×105 (S/cm). and a viscosity of from about 20 cps to about 1,000 cps.
Abstract:
Processes for purifying diketopyrrolopyrrole (DPP) copolymers are disclosed. An organic phase containing the DPP copolymer is treated with an aqueous ammonia solution and then with a palladium scavenger. The DPP copolymer is then isolated, and has a very low palladium content. The resulting DPP copolymer has high mobility.
Abstract:
A process for making a latex emulsion including contacting at least one amorphous polyester resin with at least two organic solvents to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, and separating the solvent from water. Further, the process is carried out above the resin Tg for making the latex, which drives the latex particle size under 100 nm, where toners made from the latex show improved charging performance.
Abstract:
The present disclosure relates to a toner design for a clear UV red fluorescence toner having a high lanthanide complex pigment loading, including methods of making the fluorescence toner using a saccharide or a sugar acid to avoid complexation of lanthanide ions from the pigment, with lower aggregation and coalescence temperatures in the preparation of toner particles, where the particles exhibit a narrow size distribution and good xerographic performance.
