Abstract: A rosin-modified phenol resin (A) is a reaction product of a rosin (b), a phenol (c), a formaldehyde (d) and a polyol (e), wherein the rosin (b) contains 0.1 to 3.5% by mass of a monoterpene (a1) and a sesquiterpene (a2) relative to the total weight of the rosin, and Mw/Mn which is the ratio of the weight average molecular weight (Mw) and the number average molecular weight (Mn) is 10 to 60.

Abstract: The specification describes a process for making gelled ink resins which exhibit improved properties such as lower viscosity under low shear and less viscosity decrease with increasing shear. In a preferred embodiment, a rosin-based or hydrocarbon-based resin is mixed with an organic solvent and reacted with a polyamine reactant, such as melamine-formaldehyde resin or hexamethylene diamine, under conditions sufficient to produce a substantially covalently cross-link gelled resin. The resulting gelled resin resists viscosity breakdown under high shear conditions and may be used directly for making ink compositions, obviating the need for further gelation and avoiding the use of conventional organo-metallic gelling agents.

Abstract: A toner composition for use in electrophotography comprises a rosin modified styrene-acrylic binder resin which has been prepared by steam stripping a mixture solution polymerized styrene acrylic copolymer resin, rosin and a suitable solvent such a toluene or xylene followed by cooling and grinding to form styrene acrylic/rosin binder resin. This binder resin is then formulated with conventional coloring pigments, charge controlling dyes and carriers such as iron powder or glass beads to provide dry toner compositions of high positive charge. An important feature of the present invention is that the styrene acrylic/rosin binder resin will have an inherent positive charge of at least 2.0. This inherent positive charge is in contrast to typical prior art toner binders which are inherently negatively charged.
