Abstract

Production method for tickets used for transport or entry or for other documents of equivalent value, with the object of either preventing or making it more difficult to re-use it after stamping it for devaluation. The ticket or the paper used for production has an application of magnesium trisilicate as a base layer at least on that part of its surface used for applying the control stamp. On to this base layer a further layer of print lacquer or another binding material with breakable micro capsules containing an invisible ink material embedded in it. This method ensures that when a mechanical pressure is exerted on to this double layer the colour is changed or it acquires a colour, through the breaking of the micro-capsules and the reaction of their contents with the base layer material.
