Gelled Correctable Inks

Gelling agents, including aluminum stearate, silica, and bentonite, improve the lift-off correctability characteristics of transfer medium inks.

For lift-off correctability, the transferred marking material should not soak into the paper. Typical correctable inks are transferred in a solid or highly viscous condition. Where the transfer is effected by or includes significant pressure or increased heat, the fluidity can be controlled to prevent soaking by the use of a compatible gelling agent in the particular formulation. Aluminum stearate, silica, or bentonite function well as gelling agents with organic resins and natural and artificial waxes, major ingredients of the marking materials of many correctable transfer medium formulas.
