    Abstract: Ultraviolet light-curable deposits are printed onto a substrate in a predetermined pattern to make tactile marks (e.g. Braille-like resin dots) for use by people with impaired vision to, for example, recognize the denominations of banknotes. The deposit demonstrates high adhesion due to: (1) presence of 20-80% (wt.) of a low viscosity acrylate component to provide a substrate-penetrating property; and, (2) 2-30% (wt.) of an adhesion-promoting acid acrylate. The deposit material further includes 1-30% (wt.) of urethane acrylate, 1-30% by weight of reactive diluent, photoinitiator and 1-10% (wt.) of rheological adsorbing additive. Optimally, the adhesion promoter is added after the other components have been mixed with the rheological additive. The printing step may be followed by heating before the curing step to increase penetration of the ink into the substrate. The deposit may comprise a taggant for use as a security feature.
