Dynamic Colour Shift G-switch
A security feature of the banknotes on the polymer substrate in the form of an image which changes its colour, when changing the angle of view. The effect is achieved due to the “multilayer” structure of the coating and may be seen, when changing the angle of view (fig. 11). It is similar to OVI for the banknotes on the paper basis.
