  • Emulsion aggregation toner comprising hybrid latex
    Patent number: 9280076
    Abstract: A toner includes a core including a homogenized mixture of a first polyester latex, a styrene/acrylate latex, and a compatibilizing agent latex that includes a graft polyester-styrene/acrylate copolymer and a shell that includes a polyester latex. A process includes (1) homogenizing a mixture to form a plurality of core particles, the mixture including a first polyester latex, a styrene/acrylate latex, and a compatibilizing agent latex comprising a graft polyester-styrene/acrylate copolymer and (2) adding a shell polyester latex to the plurality of core particles to form a plurality of core-shell structures.

  • Toner process comprising reduced coalescence temperature
    Patent number: 9122179
    Abstract: A method of forming toner particles includes aggregating a mixture of a latex, a wax, and an optional pigment to form pre-toner particles, and coalescing the pre-toner particles at a substantially constant target temperature selected within a range from about the glass transition temperature of the pre-toner particles to about 75° C., thereby creating toner particles having a substantially constant particle size distribution during the coalescing step.

  • Co-injection molding process for manufacturing complex and lightweight parts
    Patent number: 6248289
    Abstract: A method for molding relatively complex and large shapes by a co-injection molding process which results in a significantly less expensive and lighter molded product. The process steps include first injection molding a thermoplastic material highly densified with ceramic or stainless steel particulate material to form a shell structure having a homogeneous dispersion of the ceramic or stainless steel material within its matrix and then injecting a significantly less expensive material into the core of the preformed thermoplastic/ceramic or stainless steel structure and thereafter sintering the resulting molded structure. The resultant structure is a hollow shell of highly densified ceramic or stainless steel.
