Abstract
This invention relates to an aqueous correcting fluid, the use of which prevents bleeding of aqueous ink dyes during correction of writing errors or erasure of documents using white out. This is accomplished according to the present invention by the fact that the correcting fluid contains an anionic or non-ionic active binder plus an aminosilanes. The aminosilane-modified correcting fluid of this invention may be substituted for solvent-based fluids, without adversely affecting other properties such as water resistance, opacity and curing.
