SUBSTANCE: invention relates to the field of protection of valuable documents against forgery. The valuable document comprises on its surface an invisible protective marking applied on the elongated section along the long side of the document, which is intended for the instrument reading. The protective marking has the property of selective absorption of the radiation in the range optical spectrum from 0.76 mcm to 10 mcm.

SUBSTANCE: invention relates to a method and also the device for colour individualisation of security documents, as well as to security documents for colour individualisation with the body of the document. The starting materials are located inside this document body, which by localised targeted energy input are excited to create or modify the nanoparticles of different type and/or local concentration while the colour perception of the nanoparticles depends on their type and/or local concentration. For individualisation of such security document with such document body, the energy is injected locally purposefully into the place where in the document body the colour perception should be achieved in order to keep the individualising information through the achieved colour perception. At that, to achieve the colour change the dependence of absorption of light by nanoparticles on the wavelength is modified, which is not only the change in the absorption efficiency in the absorption spectrum, the colour change is due to the quantisation effect of the nanoparticles, and the colour perception is set by the energy input.
EFFECT: proposed invention provides the ability of colour individualisation of the document.
