Abstract

Use of the same or a similar adhesive as a tackifier in the ink as in a correction lift-off tape results in good correctability. An adhesive tape used for lift-off contains methyl ester of natural rosin, and that same ingredient, when compatible, is added to the transfer medium inks.

Tackified Correctable Inks

Use of the same or a similar adhesive as a tackifier in the ink as in a correction lift-off tape results in good correctability. An adhesive tape used for lift-off contains methyl ester of natural rosin, and that same ingredient, when compatible, is added to the transfer medium inks.

For lift-off correctability, the tackifier should not undesirably increase the adhesion to the paper. The transferred marking material should not soak in the paper and should be internally cohesive. Such marking material is removed in a lift-off procedure by applying an element from the top which adheres to the marking material, and lifting the element away. The incorporation of a tackifier into the marking material is consistent with all these requirements.

An ethylene vinyl acetate copolymer-based ink, with methyl ester of natural rosin added, lifts off completely by the use of an adhesive lift-off tape which contains methyl ester of natural rosin.
