Abstract
A method of producing banknotes on a substrate in-line on a web-based process is disclosed, including providing a tactile layer. In addition, a banknote produced by the above method, a banknote having a single-ink system, a coating for banknote and a tactile security feature are disclosed.
Claims10
A banknote comprising:
- a substrate;
- a printed indicia layer;
- a printed tactile paper-feel layer extending over a surface of the substrate except in at least one selective area including a security feature, the printed layers at least partly overlapping and in contact with each other;
- wherein, in overlapping regions, the print layers are partially dissolved into one another;
- and,
- each of the printed layers includes an ink having Hansen Solubility parameters within the following ranges:
- δd—between 17 and 19, δp—between 9 and 11 and δh—between 5 and 7.

A banknote comprising:
- a substrate;
- a printed indicia layer;
- a printed paper-feel tactile layer extending over a surface of the substrate, printed layers at least partly overlapping and in contact with each other;

A banknote comprising:
- a polymer substrate;
- a printed indicia layer;
- a printed tactile paper-feel layer extending over a surface of the substrate, each of the printed layers at least partly overlapping and in contact with each other;
- wherein, in overlapping regions, the printed layers are partially dissolved into one another;
- and
- each ink having Hansen Solubility parameters within the following ranges:
- δd—between 17 and 19, δp—between 9 and 11 and δh—between 5 and 7, and wherein the printed tactile paper-feel layer provides an increased surface roughness to the polymer substrate and a coefficient of friction between the banknote and another of the same banknote of between 0.2 and 0.4.
