Abstract
The present invention is directed to correction tapes having dye migration blocking properties. More specifically, the present invention includes a correction tape having a dye migration barrier. The dye migration barrier comprises an organic material that serves as a physical barrier to prevent dye from migrating from the lower corrected layer to the visible surface. Additionally, the present invention is directed to a process for the manufacture of a correction tape having a dye migration barrier.
Claims16
A correction tape comprising:
- a first layer which is a support member with sufficient rigidity to hold at least a second, third, and fourth layer;
- the second layer comprising a correction medium layer;
- the third layer comprising a dye migration barrier;
- and
- the fourth layer comprising a pressure sensitive adhesive layer present in sufficient amount to form a layer of a thickness to adhere the second and third layer to a substrate,
- wherein the second and third layers are interposed between the first and fourth layers.

A correction tape comprising:
- a first layer which is a support member with sufficient rigidity to hold at least a second, third, and forth layer;
- the second layer disposed upon the first layer is an organic polymer layered to a thickness sufficient to mask printed or ink matter on a substrate to form a correction medium layer;
- the third layer disposed upon the second layer is a dye migration barrier layered to a thickness sufficient to prevent ink from traversing from the substrate and through the second layer;
- and
- the fourth layer disposed upon the third layer and which is a pressure sensitive adhesive present in sufficient amount to form a layer of a thickness sufficient to adhere the second and third layer to a substrate.
