ACID-BASE PROPERTY CONSIDERATIONS FOR IMPROVED ADDITIVE ATTACHEMENT ON TONER

ACID-BASE PROPERTY CONSIDERATIONS FOR IMPROVED ADDITIVE ATTACHEMENT ON TONER

A developer comprised of a toner and at least one external surface additive, wherein an acid-base interaction has an Interaction Surface Parameter (ISP) of greater than 0, and wherein ISP is defined by the following equation: [(Ka)tonerx(Kb)additive]+[(Kb)tonerx(Ka)additive]-[(Ka)tonerx(Ka)additive]...

Zusammenfassung:A developer comprised of a toner and at least one external surface additive, wherein an acid-base interaction has an Interaction Surface Parameter (ISP) of greater than 0, and wherein ISP is defined by the following equation: [(Ka)tonerx(Kb)additive]+[(Kb)tonerx(Ka)additive]-[(Ka)tonerx(Ka)additive]-[(Kb)tonerx(Kb)additive], wherein Ka is the Lewis acid value and Kb is the Lewis base value.
