Abstract
A security document paper (for cheques, traveller's cheques, lottery tickets, banknotes etc) includes a layer having in or on it, 2 substances capable of a distinctive colour reaction, so that, when a document is to be tested, application of at least 1 reagent will cause the two substances to react and change the colour where the reagent is applied. A positive and active test for authenticity is possible, whereas passive methods were previously used, e.g. watermarks or inclusion of coloured threads or distinctive particles.
