Beschreibung
Zusammenfassung:	A support material toner particle for use in xerographic additive manufacturing includes a polyvinyl alcohol (PVA) polymer and_blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the T g of the PVA polymer to be within about 1 °C to about 20 °C of a desired build material toner T g . A xerographic toner system includes a build toner material and a support toner material, the support toner material includes a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the T g of the PVA polymer to be within about 1 °C to about 20 °C of the build material toner T g . A method of making a support toner material includes blending polyvinyl alcohol with blend additives including a chitosan and polyvinylpyrrolidone and forming support toner particles after the blending step.
