Abstract (en)

[origin: EP0913735A2] Dry toner particles with a resinous matrix containing a mixture of a polymer (LPC) with low softening point and tg delta > 3, modified by a modifier (D) selected from the group consisting of long chain aliphatic compounds with a reactive end group and having between 20 and 250 carbon atoms and a polysiloxane, said modifier and said polymer being present in a molar ratio LPC/D between 0.8 and 1.25 and a non-linear polymer with a softening point TsB such that 110 DEG C ≤ TsB ≤ 135 DEG C. The toner particles further contain a wax chosen from waxes having a melting point near to the softening point of the branched polymer B.
