摘要： A sheet material, such as a bank note, having tactile indicia therein, the tactility of which is resistant to deterioration and usseful for assisting persons with impaired vision to identify one or more predetermined characteristics of the sheet material such as a bank note. The sheet material has therein at least one embossment forming the indicia and comprises a first surface and a second surface, with one of the surfaces defining a cavity in the area of the embossment. A layer of reinforcing material is provided to at least the area of that surface which comprises the cavity. Once the reinforcing material is dried and/or cured the embossment (indicia) is strengthened by the layer of reinforcing material and thereby rendered more durable when the bank note is subjected to the wear of circulation. The reinforcing material may be selected from the group consisting of varnishes, inks, adhesives and caulking compounds.
