Abstract
Intermediate binder composition for use in toner compositions, comprising (a) a block copolymer comprising one predominantly poly(monovinyl aromatic) block per molecule and one predominantly poly(conjugated diene) block per molecule, the latter blocks being selectively hydrogenated to a residual unsaturation degree of 20% or lower, in an amount of from 5 to 35% by weight relative to the weight of the intermediate binder composition, and a microcrystalline wax, having a weight average molecular weight of from 1000 to 10,000, and having a drop point of 75.degree. C. or higher (measured according to ASTM D 3104), in an amount of from 95 to 65% by weight relative to the weight of the binder composition.
